Non-disruptive backup
This patch adds support for non-disruptive backup for
volumes in 'in-use' status as follows:
Adds a force flag in create backup API when backing up
an 'in-use' volume.
For the default implementation in volume/driver.py:
* Create a temporary volume from the original volume
* Backup the temporary volume
* Clean up the temporary volume
For the LVM driver:
* Create a temporary snapshot
* Obtain local_path for the temporary snapshot
* Backup the temporary snapshot
* Cleanup the temporary snapshot
Attach snapshot will be implemented in another patch.

Dell SC: Fix Consistency Group issues
The Dell Storage Center driver was not honoring the consisgroup_id
in the volume object in volume creation. Updated create_volume,
create_cloned_volume and create_volume_from_snapshot to honor this
value.
The driver was also not checking that volumes were initialized prior
to snapshotting a consistency group. The Dell backend does not
actually create the volumes until there is data or the volumes are
mapped to a server.
On create_volume_from_snapshot the driver was not checking for
cgsnapshot_id before snapshot_id.
Changed from calling the db to update snapshots to retrieving
the SnapshotList() object.
In addition some tests were not checking results. Fixed that.

Prevent missing Purity hosts from raising errors
Occasionally a Purity host can be deleted out from underneath Cinder.
When this happens if cinder is attempting to disconnect a volume from
that host we should treat it as a ‘success’ since if the host is gone,
it is disconnected already (as far as Purity is concerned).
To prevent one cause of this, the disconnect method will now be locked
with the connect ones so that can’t delete a host we intend to re-use.

Refactor Huawei Volume driver
This patch attempts to refactor Huawei volume driver in liberty.
We add a base driver to implement the basic functions.
The sub-class will inherit from the base driver according to different
storages.
The following changes were made in this refactor:
1. Abstract a base class named HuaweiBaseDriver to make Huawei driver more
universal. You can find it in the huawei_driver.py.
2. Put all static variables into the constants.py.
3. Rename rest_common.py to rest_client.py. rest_client.py stores the
relevant methods implemented for Huawei driver.
4. Migrate some public methods from rest_client.py to huawei_utils.py,
such as parse_xml_file(), _get_volume_type() and so on.
5. This refactor only involves structural adjustment and does not involve
functional changes.

Handle volume not found on zfssa volume delete
The zfssa driver doesn't handle cases where a volume may not
exist on the backend when a delete call is sent. The result
is a stack-trace in the logs, sometimes a crash of the service

This patch doesn't address the root cause of the issue, but
it does handle the case more gracefully by catching the
exception, logging an error and returning.
This way the volume can be cleaned up on the Cinder side and
the operator still has an indication that something went wrong.
This is a common pattern for most of the drivers in Cinder.

Fix saving tz aware datetimes in Versioned Objects
Currently we cannot save date fields in Versioned Objects because they
are timezone aware and our database is not.
If we look at our objects definition, we are not giving any value to
tzinfo_aware argument, so it takes DateTime default value (True).
In our sqlalchemy model definitions we are defining our datetime fields
as Column(DateTime) which will take sqlalchemy default: class
sqlalchemy.types.DateTime(timezone=False)
In most cases we are accessing those fields directly through the DB
methods, so we don't see the problem, but if we were to modify any of
those fields using versioned object, for example scheduled_at, and then
save the object we'll get an exception:
File ".../sqlalchemy/sql/type_api.py", line 278, in compare_values

Because we are trying to save a timezone aware date to a timezone
unaware DB field.

instead of overwriting obj_get_changes, that returns all datefields as
timezone naive UTC datetimes ready for saving.
