HP3Par: Set snapCPG when managing existing volumes
This fixes a corner case where the user did not assign a "Copy CPG"
value to the volume when originally created on the back-end, and
then the user does not assign a "Volume Type" to the volume
when it is then "managed" into OpenStack.
This results in an undefined "snapCPG" value which means no
snapshots can be created for the volume.
The fix is to set the "snapCPG" value to match the "User CPG"
value associated with the volume when the volume is "managed"

Add completion logging for snapshots and volumes
While trying to debug insufficient resource issues occasionally
seen in the gate, it was noted that there's no logging for
resource deletion of volumes and snapshots.
This patch adds some simple logging in the cinder.volume.api
to note when and why a delete call might fail as an info
message indicating when the request is successfully issued
to the scheduler/rpc layer.
In addition, this patch also adds the same sort of logging
to the LVM backend driver.
This additional logging will help troubleshoot the current
resource issues/races we're encountering in the gate.

Create SolidFire Template account on init
The standard flow in the SolidFire volume is to create
accounts dynamically as needed based on project id.
Unfortunately the clone_image method "forgot" about this

The clone_image method is enabled using a specific account

Raise correct exception when validate_connector failed
Cinder volume manager uses validate_connector() method to verify if required
information is in connector when handling initialize_connection() request.
validate_connector() is actually a pure input validation method, basically
checking if 'initiator' or 'wwpns' is in connector if storage protocol is
iSCSI or FC. However, when required information is missing, currently drivers
raises either VolumeBackendAPIException or VolumeDriverException, which would
then bubble up to API and then to user (Nova) as InternalServerError.
This change adds a new exception - InvalidConnectorException, that drivers
should raise when connector is found not valid. With that, Cinder API would
raise BadRequest instead to user, suggesting things are missing in request.

Add provisioned_capacity
This change is needed by the over subscription patch:
https://review.openstack.org/#/c/142171/
This patch makes the following change:
Add 'provisioned_capacity' to Cinder base driver, Cinder reference
driver (LVM), and scheduler host_manager.
provisioned_capacity is the apparent allocated space indicating how
much capacity has been provisioned.
Example: User A created 2x10G volumes in Cinder from backend A, and
user B created 3x10G volumes from backend A directly, without using
Cinder. Assume those are all the volumes provisioned on backend A.
The total provisioned_capacity will be 50G and that is what the driver
should be reporting.
