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.

Check for empty attributes on SF volume

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.

Huawei: fix multi REST-URLs bug
Huawei driver now supports multi REST-URLs, which means users can

But if the chosen REST-URL has some failures, Huawei driver can
not change to another REST-URL automatically.
To resolve this, rewrite the "call" function in rest_client.py of
Huawei driver. If REST command failed to send, driver will do a
"login" process to set up another connection, and send the failed
command to a new REST-URL again.
And change REST command timeout to 52s, change login timeout to 4s,
to avoid long time waiting for failure.

The 3PAR drivers don't work with this currently because of the way volume
cloning works in the drivers. When a volume is cloned, it's done so

The problem is, a background cloning also locks the original volume from
being modified. The generic image cache does a clone, and then an extend
volume, which fails for the 3PAR drivers currently.
