Don't fail target_delete if ACL's don't exist
Seen in the gate a bit where a target delete is called and fails because

Use snapshot object in create_volume flow
create_volume flow was making a call to db.snapshot_get to get
a snapshot dict and passing it onto drivers in
create_volume_from_snapshot() instead of an object. This causes
a conflict for some drivers, since create_snapshot and
create_volume_from_snapshot methods have two different snapshot
types (object vs. dict). The following patch fixes this by using
objects in create_volume flow and allows drivers to be updated
appropriately to use snapshot objects.
The strings can be got from the [DEFAULT] section or a driver instance group
section.
If the string can not be found in the cinder.conf, it will try to find a
default filter_fuction or a default goodness_function which can be specified
in the driver code. HP3par drivers don't provide default values. However if
other driver want to provide default values, it can be done by overwriting
get_default_filter_function and get_default_goodness_function.
2. Also added goodness_function and filter_function to the
_update_volume_stats in ISCSIDriver, FibreChannelDriver, FakeISCSIDriver
and LVMVolumeDriver.
3. Added 2 stats total_volumes and capacity_utilization so they can be
used as the part of the formula in filter_function or goodness_function
string.
4. Fixed free_capacity for limited cpg to include SDUsage's usedMiB as part of
the calcuation so it is consistent with unlimited cpg and capacity_utilization
looks better.
5. Added total_volumes capability to the LVM driver.

Make objects behave more like our old dictionaries
Prior to Cinder Objects we passed a dictionary representation
of a Cinder resource around. There are a few places where we
abuse this a bit and do things like "ref_dict.get('some-key', None)"
to reuse some code and determine if for example the object is
a snapshot or a volume (based on it's keys). This is probably
a pretty lazy/bad idea, but we have cases where we do it,
such as in the SolidFire driver and it looks like maybe some
calls in the profiler.
For now, we just make the compatibility shim in Object base truly
compatible and return None for non-existent attributes rather
than raising. Follow up work would be to clean up all of our
usage to strictly use objects and get rid of the compatibility
shim altogether.

Dell SC API change fails snapshot creation
The Dell Storage Center driver is failing snapshot creation on

The doNotExpire option was removed in API 15.3.1.110. We were
setting this so that the replays are not expired and removed when
Cinder expects them to still be there. This has been replaced by
setting expiretime to 0. We were doing this already so the fix
was to simply remove doNotExpire from the REST request payload.

Clear migration_status from a destination volume if migration fails
When some error happens during volume migration, cinder-volume
keeps remaining a destination volume because the volume copy may be
in the completing phase and a source volume may be deleted already.
In this case, the migration_status of the destination volume in
data base should be cleared. As a result, the volume can be handled
properly even if volume migration is failed. If the migration is
in the migrating phase, the volume should be deleted and an entry
of database is also destroyed because the source volume is remaining.
Also there is an another problem that a source volume is remaining
as migrating status if create_export raises exception. In this case,
source volume can't be deleted even if it will be unnecessary.
