Check for empty attributes on SF volume
This should not happen, but; we should be more strict
about our dict reading/checking and always make sure
the key item actually comes back and exists.
In the case of volume['attributes'] we were always
assuming this to be present which should be "ok", but
it's better to verify if rather than assuming, so this
patch adds a simple verification step before trying to
fetch on volume['attributes'].

Provider_id info isn't necessarily reliable when dealing

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.

Add migrate_volume to BaseVD

This patch disables the 3PAR drivers if an admin tries to
enable the generic image volume cache capability.
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
in the background, which makes the clone available immediately for attaching.
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.

Add mechanism to update snapshot provider_id

Commit 212aff327a36f925be3be69b9b54b946dbdd5c2a replaced
'cinder.openstack.common.fileutils.file_open' with 'open'
from builtins. It also updated unit tests to patch 'six.
moves.builtins.open' instead of 'cinder.openstack.common.
fileutils.file_open'. This resulted in intermittent failure
of test 'test_create_backing_from_stream_optimized_file'
in VMwareVcVmdkDriverTestCase. The failure happens because
the test patches 'open' from builtins and tests code which
throws an exception in a 'with open(...)' block. This
exception is handled in excutils.save_and_reraise_exception
which uses 'with open(...)' and the exception handling
fails due to the global patching of 'open'.
This patch replaces the global patching of builtins 'open'
with a patch decorator which binds 'open' to the namespace
of the code under testing.
Volume creation will fail if the VMDK driver selects

This may happen even if there are usable ESX hosts
