EMC VNX Cinder Driver Update
VNX Direct Driver was contributed in Icehouse and updated in Juno.
This commit is to continuously improve the driver with the
following enhancements in Kilo:
* Performance improvement, especially the synchronized operations
initiatlize_connetion and terminate_connection.
* LUN Number Threshold Support
* Initiator Auto Deregistration
* Force Deleting LUN in Storage Groups
* Code refactor to enhance the robustness

Roll back if VMAX masking view not created
In emc_vmax_masking.py, an exception object is created if
there is a failure in the masking view creation logic.
However, the exception is not raised. As a result,
initialize_connection will succeed in spite of a failure
but the VM will not be able to access the disk.
This patch adds rollback logic to handle failures in
creating masking view. If the masking view cannot be
created, the volume will be added back to the default
storage group and an exception will be raised.

Support iSER driver within the ISCSITarget flow
Currently the iSER driver is supported over TGT only,
and there are a couple of iSER classes that inherits
from iSCSI classes, but most of their functionality is
the same as the iSCSI classes. This code duplication caused
instability in the iSER driver code, when new features or
changes are added to the iSCSI driver flow.
Main changes:
1. Added a new parameter to volume/driver.py in order to
set the iSCSI protocol type to 'iscsi' or 'iser', with default
to 'iscsi'.
2. Configured TGT VOLUME_CONF and VOLUME_CONF_WITH_CHAP_AUTH
with the new iSCSI protocol parameter.
3. Added support for RDMA (using iSER) to cinder-rtstool.
4. Set "driver_volume_type" to "iscsi" or "iser" value, according
to the new parameter value.
5. Added unit tests for the new iSER flow.
6. Added deprecation alert to ISERTgtAdm.

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"

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.

This patch makes the following change:
Add 'provisioned_capacity' to Cinder base driver, Cinder reference

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.
