Fix update Huawei driver issue
If a volume is created with old version of Huawei driver,
there is no pool info related to the volume, but the new
version of Huawei driver assumes that the volume have the
pool info and will read the pool info from the volume,
and then the read fails. This will happen when we call
create_volume_from_snapshot() in new version of Huawei
driver when the volume is created by old version of Huawei
driver.

Show image metadata

Currently the volume related operation in CloudByte driver does not:
* Update the ISCSI Initiator Group during volume deletion operation,
and
* During retry of any volume operation it does not catches the exact
cause of the failure happened.
So to deal with the following issues two changes has been done in
CloudByte Driver:
* Added a new method "_update_initiator_group"
ISCSI Initiator Group is one of the parameter added to the volumes
at the time of creation in CloudByte Storage. Using this the external
source can access the volumes easily. By default, Initiator Group
value is set to 'ALL', but it should be changed to 'None' before
deletion. Since the following is not happening, thus volume delete
operation fails from OpenStack. In order to avoid this the
"delete_volume" method now uses the "_update_initiator_group" which
update the volume ISCSI Initiatior Groupof the volumes to 'None'
before deletion, and thus volume delete operation will have no issues
while running from OpenStack.
* Added a check to "_retry_volume_operation"
The _retry_volume_operation method was not able to check the exact
cause of the failure happened during volume operation in CloudByte
Storage, which arises if some invalid parameters are provided in
"cinder.conf" against "cloudbyte backend" or if some anomaly happens
at CloudByte Storage during any volume operation from OpenStack. Due
to this, tracking the ERROR becomes a very difficult task to do. Thus
to resolve this issue a "check" has been added to the method which
will raise the exact cause of the error and thus making it easier to
solve.
This patch cleanly reverts the changes made via the
commit: e681ba2a99995dcd999e6539bb1222f8a1ac8adc
cleanly and mitigates the conflicts that would
occur with git-revert on the said commit.
The revert is solely for changes pertaining to the use
of the external library, netapp_lib. Minor code refactors
from the prior change are retained.
Unit test coverage has been increased for ZAPI and REST

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.

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.

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
