LeftHand: Implement un/manage snapshot support
Implements support for managing and unmanaging snapshots to

This patch now allows snapshots to be removed from OpenStack
management but still left on the LeftHand backend. Snapshots
on the LeftHand backend can also be managed by OpenStack.

Fix variable scope issue in try-except
Below piece of code in cinder.backup.api.API.create does not handle
the scope of variable 'backup' properly. In general variable used in
except clause has larger scope than what is in try clause.
The first problem: if object.Backup.__init__ raises exception,
variable 'backup' won't be assigned. However the cleanup code invokes
backup.destroy(), which results in an UnboundLocalError. The original
exception of __init__ is dropped, instead UnboundLocalError is raised
up-level. I know that for now objects.Backup.__init__ doesn't have
chance to raise exception, but when writing code we should not rely
on such assumption.
The second problem: backup.create() invokes DB. If an DB exception is
raised, backup.id won't be assigned. Any access to backup.id will
result in an "NotImplementedError: Cannot load 'id' in the base
class". However, when cleaning up, the backup.destroy() does access
backup.id. So we have the similar problem as the first one, and the
original exception is overrode by NotImplementedError.
This patch fixes it by adding a first-assignment outside try clause,
and add a safe check in except clause. The added test cases, if run
on the original code, it will show how the above problem occurs.

Bootable filter for listening volumes from CLI
Currently cinder treats all values passed to it as True

'True' and 'False' values seperately.
Existing behavior will be kept same.
Only True/False/true/false input handling is done to treat

Don't create cgsnapshot if cg is empty
If we create cgsnapshot from an empty consistencygroup, it fails
with "Consistency group is empty. No cgsnapshot will be created".
However, a cgsnapshot object is still created in DB.
This is because in cinder/consistencygroup/api.py::_create_cgsnapshot,
we create cgsnapshot object before we test whether the corresponding
consistencygroup is empy.
This patch fixes this problem by moving the creation of cgsnapshot
object to after the test of whether consistencygroup is empty.
This patch fixes the problem with the 3PAR not
working with the generic image cache.
In order to do the image cache, the 3PAR has to create a
temporary snapshot of the volume being cloned. Then the
background cloning is against the temporary snapshot.
The problem is, the temporary snapshot stays around.
We try to account for this temporary snapshot in
the delete volume action.
We also bump the minimum required python-3parclient
version to 4.1.0, which has the new getVolumeSnapshots
API call required to make this all work.
Currently the volume manager doesn't log the instance ID during
volume detach. This is missing in cinder-api log as well. This
patch adds a log statement to print a message with volume ID and
instance ID before calling driver detach.

Pin RPC and object version to lowest running
This commit adds detection and pinning to lowest RPC API version to all
rpcapi modules. The version pin is determined by a DB call done once per
service lifetime thanks to caching. Handling the compatibility is
guaranteed by oslo.messaging and our shims in rpcapi modules.
To achieve o.vo compatibility, a similar approach is implemented. Custom
oslo.messaging serializer is implemented that backports objects to the
lowest running version on sending.
During the process of upgrade it may happen that manager receives an
object in the version lower than current one. Handling of such
situations is up to the manager and it should do that explicitely by
checking obj.VERSION.
The patch also adds required methods to db.api and Service object.

Report RPC and objects versions
While doing a rolling upgrade we will have services running in various
versions. In order to determine how to downgrade the RPC request and
payload (objects) to the lowest common version we need to actually
report versions of RPC servers (managers).
This commit implements such reporting in generic cinder.service module.
It is using DB columns that were merged in Liberty to save this
information.
To have a single version string identify a set of o.vo versions we need
to have dictionary with objects versions history. In that purpose a
dict-like CinderObjectVersionsHistory class and OBJ_VERSIONS instance of
it is added to cinder.objects.base. A unit test enforcing bumping the
versions is also included with the patch.

Huawei: Balanced FC port selection when zoning
Currently we always select the first two FC ports
from every controller when zoning, the rest FC ports
of the controller will never be selected. This patch
will calculate each port's load and select the first
two smallest load ports.
VNX cinder driver also supports failover back and forth
NOTE: you can only place one replication_device for each backend since
VNX driver only supports 1:1 fanout ratio. Only synchronized replication
is supported in this patch.
replication_device describes the target array for replication. This can
be either another managed cinder backend or one not managed by cinder.
The above settings will cause a protection group to be created between
the two flash arrays. It will replicate any volumes placed in it with
settings that cause a volume to be replicated every 15 mins (900s). All
snapshots will be kept for 4 hours (14400s). Then 3 snapshots per day
will be kept for 7 days.
Note that replication-failover is supported from primary to any of
multiple secondary arrays, but subsequent replication-failover is
only supported back to the original primary.
