Missing configuration opts from cinder.sample.conf
The logic for writing opts registered with register_opt() to the
auto-generated opts.py file was flawed in that the directories where
there were opts being registered with this method would be imported,
but the actual opt would be missed when looking through the file for
the name of the opt being registered. Now the singular opts are being
caught and written to opts.py for the oslo-config-generator to process.
The 'backend' section was added to generate_cinder_opts.py
due to some of the missing opts being a part of that section.
Also the way some of the opts that were being registered with groups
were incorrect and so this addresses those in both how they were
processed in generate_cinder_opts.py and the files in which they are being
registered.
There is also one change to the name of an opt in cinder/volume/api.py.
Instances such as this one will be caught by the in-progress hacking

Create volume in cg enhancement in VNX driver
VNX driver queries whether a LUN is in CG after adding it into

Allow c-vol backends to start when some backends fail to load
Currently, if a c-vol backend fails to load due to an error in
the module startup process (like a volume driver's __init__ or
dependency import failure), the c-vol process halts completely.
Instead, catch that backend failure, log it, and allow other
backends in enabled_backends to still start up and run.
Note that this is not applicable for failures that allow
drivers to load and remain "uninitialized" -- this is for
failures that occur prior to that point.
When using NetApp drivers, all available flexvols on
a datastore are being reported to the Cinder Scheduler
as available storage pools. This allows Cinder volumes
to be created on flexvols not designated for OpenStack.
This commit fixes the problem by delimiting which pools are
eligible for provisioning via a configuration parameter
'netapp_pool_name_search_pattern'. This allows
the Cinder drivers to operate against a restricted
set of storage containers.

NetApp volume/snapshot delete performance fix
cDOT NFS NetApp drivers back cinder volumes with array-side files and
use array-side cloning techniques when creating snapshots and when
creating volumes from glance images. Customers have experienced
performance issues on the array when deleting many of these in
in quick succession, especially for large volumes.
This commit addresses these performance issues by overriding parent
class volume and snapshot delete methods, which use OS "rm" command to
delete volume backing files, with methods that use DOT API to delete
these files, and which invoke the optimized file deletion engine
available in DOT 8.3.

Replace soft_delete in volume_type_access_remove
This commit replaces oslo.db's soft_delete used in
volume_type_access_remove in db.api with a simple update setting
deleted column to True.
As deleted column is boolean it is represented in the DB by TINYINT,
which max value is 127. This introduces problems when removing records
with id higher than that, because soft_delete sets deleted column to the
value of id. This commit fixes the issue and adds unit tests for such

Dynamically create cinder.conf.sample
As it stands, the opts.py file that is passed into
oslo-config-generator isn't being generated dynamically
and the old way of generating the cinder.conf.sample is
dependent on oslo-incubator which Cinder is trying to
move away from. oslo-config-generator works differently
than oslo-incubator so a number of changes had to be made
in order to make this switch.
This patch adds the config directory to Cinder and in it
are two files:
-generate_cinder_opts.py that will take the
results of a grep command to create the opts.py
file to be passed into oslo-config-generator.
-cinder.conf which is the new configuration for
oslo-config-generator. The file is inside the config
directory to be consistent with other projects.
Some changes were made to the generate_sample.sh file in
order to give the base directories and target directories
to the generate_cinder_opts.py program.
tox.ini was edited to remove the checkonly option because
all that needs to happen in check_uptodate.sh is a check to
ensure that the cinder.conf.sample is actually being
generated with no issues.
All options were removed from the check_uptodate.sh
because they were unnecessary given the new, more simple
way of generating the cinder.conf.sample.
setup.cfg was also edited in order to add information
oslo-config-generator needs to run.

NetApp: Fix volume extend with E-Series
Thin provisioned volumes were being converted to thick provisioned
volumes by extend_volume. When thin provisioning support was added,
the extend_volume method was not updated to use the correct API
for performing the capacity expansion operation.
This patch changes the volume extension strategy when a volume is
thin provisioned to use the correct API. With a thick provisioned
volume, a clone will be created with the new capacity, and the old
volume removed, but a thin provisioned volume's capacity can simply
be expanded directly, because that is merely the capacity that the user
sees, as opposed to the backend provisioned capacity.

Fix issue of volume after host-assisted migration

Local img-cache files ignored for image transfers

Fix NetApp clone from glance failure
When glance and cinder are backed by the same NetApp DOT flexvol
container, exposed as an NFS share, a direct clone is attempted
of the backing files rather than a copy. With the advent of
kilo 2015.1.1, this clone operation fails with the message:
"Image cloning unsuccessful ... need more than 2 values to unpack."
The issue here is that the clone path code is calling the parent
nfs class _is_share_eligible() method to see if there is enough
space on the destination flexvol and this method calls _get_capacity_info()
expecting a three-tuple to be returned. However, commit e52f304313efc695f7dd89c222041bffd53c131a deliberately changed the return
values of _get_capacity_info() within the NetApp drivers to return
a 2-tuple, based on API calls to obtain capacity information from
the NetApp storage arrays. That commit missed that this method
would also be invoked by the parent nfs class _is_share_eligible()
method, which expects a different signature.
The fix in this commit is to replace the call to the parent
_is_share_eligible() method with a more appropriate NetApp class
specific _share_has_space_for_clone() method. This new method
uses the NetApp version of _get_capacity_info to get space information
from the arrays via NetApp apis and expects a 2-tuple to be returned
from this method.

Fix volume lookups in SolidFire template caching
There's a number of issues with the SolidFire template caching
code. There are a number of metadata items that aren't consistent
between Glance API V1 and V2, there's also some problems with how
the code is dealing with it's internal volume and just flat out
wrong account checking.
This patch focuses mainly on fixing up the account and volumeID
issues. The _do_clone method currently expects to find the src
volume under the same account as the dest volume. That's fine
for most cases, but doesn't work for either the SolidFire template
caching, or for the use of generic image caching in Cinder.
We fix that easily by modifying the _get_sf_volume call to have an
option to search all active volumes on the Cluster instead of just
those for a specified account. For now we only change the clone
methods, as they're the only case where we fall into the case of
cross-ownership of volumes in the same context.
The other issue is around the cleanup/delete in the case of a
failed template-volume create. In this case we were passing in
the Cinder UUID to a direct SolidFire API delete cmd, which
is wrong. The direct call for the SolidFire API call requires
that the actual SolidFire ID be used. So we leverage the modified
_get_sf_volume call here as well.
Another issue that was introduced was the introduction of
a connector object to the intialize_connection call. We
got around this once already by just passing in a fake
connector that was actually a string. That was fine, but
the initialize_connection routine also now checks the connector
for multi_attach, so it fails the _get call on a string. We
fix that by just building a dict and using that instead of
a fake string.
Finally, the method of relying on the Glance metadata virt size
has been problematic, it's not set by default, it's not accurate
and it's a bit inefficient. There have been a number of issues
with this method of size determination, so we'll dump that and
just leverage the image_utils methods directly.

Fix Pure get pgroup volume snapshot name
When creating a volume from a consistency group snapshot we have to go
look up the volume level snapshot from the group. Previously we could
just directly get to the cgsnapshot model from the snapshot. After we
switched to using the snapshot objects however we cannot do that (at
least not until we have cgsnapshot objects too).
As an interim solution we did a query to the REST API on the array to
just list all of the snapshots. Unfortunately that doesn’t work on all
versions of the Purity REST API. To have a more usable solution we need
to do a db lookup to get the pgsnapshot.
It’s not ideal, and will be removed ASAP, but for now we need to at
least not regress in functionality.
