Implement retype for Pure drivers
Currently retyping on the same backend requires a migration to occur
due to using the default implementation of retype on the base volume
driver.
Volumes on the Pure arrays do not have any differentiation
between volume types Cinder may be using. Because of this we can
implement a retype method that will be used whenever changing
types on the same backend that essentially does nothing except return.

Dell SC: Add support for driver retype
Previously there was no need to support retype by the driver
since any kind of retyping would require migration. With the
addition of the ability to set specific Storage Profiles to
use by commit Icf76fceca5a0ae20bb08b276b0c41ef6cdb31087 we
now have something the driver can handle to optimize the
retyping operation.
This adds handling for changes in the selected Storage Profile
if the backend stays the same. Any other retype changes will
return failure, resulting in it falling back to full volume
migration.

This patch adds support for non-disruptive backup for

Adds a force flag in create backup API when backing up

* 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.

Remove logging statements from migrations
One of the things that I believe is causing problems with the move to
ostestr and concurrency in unit test run is the copious amounts of
logging that is coming from the db migrations. In most cases much of
this logging doesn't really seem all that useful, a debug or info log
stating a migration failed, followed by a raise which should generate
a stack trace with the error anyway, seems we could easily do without
this.
Also the "performing migration xxxx/completing migration xxxx" doesn't
seem overly helpful either. Keep in mind that the migration engine
does some amount of logging anyway.
In addition, catching the exceptions and logging them isn't overly
beneficial or needed either. When calling migrate from cinder-manage
if one of the migrations raises an exception that will be propogated
up to cinder-manage and displayed. In other words all of the info is
already available, so there's no need to put it here.
Finally, if you take a look in general most migrations in other
projects don't LOG every thing for the same reasons.
So this patch removes logging statement from the migrations themeselves.

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.
