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.

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
and an inability to clean up volumes from Cinder's perspective.
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.
If backup cannot be found while resetting its status, Cinder
exception (BackupNotFound) is raised instead of HTTP exception.

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:

Because we are trying to save a timezone aware date to a timezone

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

Set encrypted key in connection_info during initialize
There are encrypted volume tests in Tempest which are passing
in the ceph job but the encryption providers in nova (luks and
cryptsetup) are not actually being called in nova because the
'encrypted' key isn't being set in connection_info for the Rbd
volume driver, and nova is keying off that value to determine
if it needs to run it's encryption providers.
So the tests are passing in the ceph job but it's a total false
positive and the API should actually fail - either the cinder
API to create the encrypted volumes if the Rbd volume driver in
Cinder doesn't support encryption, or the volume attach call in
nova if it can't encrypt the connected volume, either way the
test should fail until that support is baked into nova.
I'm not aware of any kind of 'supports_encryption' or 'encryptable'
capability flag for cinder volume drivers, but that might be
needed for the volume create API to fail if trying to create a
volume from an encrypted volume type where the volume driver
itself doesn't support encryption - but maybe it's only a nova
problem since nova has the encryption providers.
This is fixed generically in the VolumeManager's
initialize_connection method where we check for the encrypted
flag being set in the volume driver method and if not, the
manager sets it based on the volume.encryption_key_id value.
We do this globally since there are other volume drivers besides
rbd that aren't setting the encrypted key in connection_info,
but we test rbd in the gate via the ceph job so most of the
bug tracking is around validation of the ceph job.
