Implement retype in IBM GPFS Driver and refactor
1. Add retype method to GPFS driver. Currently only storge_pool
attribute is handled. Future patches will extend this.
2. Refactor migrate method to handle migration locally if source
and target are in the same gpfs cluster.
3. Move driver into 'ibm' directory.
4. Refactor based on pylint feedback.
5. Replace mox with mock in unit test.
6. Improve exception handling and logging.
This patch adds the required initiator target map
for the Fibre Channel Zone Manager. The
FCZM looks for the initiator_target_map to try and
automatically zone up the endpoints.

Driver for IBM SONAS and Storwize V7000 Unified
The IBM NAS Driver currently implemented to work over NFS protocol,
and implements required set of features for OpenStack Icehouse release,
using the features of these storage products. It allows IBM® SONAS®
and Storwize® V7000 Unified filers to host storage for OpenStack
environment by integrating with Openstack Cinder service.
Creating FC connections was not working due to several issues:
1. The lsfabric command in the Storwize/SVC omitted the delimeter and so
the output was not correctly parsed by the driver.
2. In some cases comparisons of WWPNs were not case insensitive - ensure
we compare lower-case WWPNs.
3. If the host supplied extra information in the connector (e.g. iSCSI
initiator name in case of an FC setup, or FC WWNNs/WWPNs in an iSCSI
setup), the driver would try to make those host mappings on the storage
too. This could lead into unwanted behaviour and confusing error
messages (for example, in an FC setup reaching the maximum number of
iSCSI mappings).
In addition, unit tests weren't properly testing FC - instead they were
always testing iSCSI due to an error in parsing extra_specs. This patch
fixes that error and the unit tests as well.
These changes must all be made together for unit tests to pass.
Allows automated zone lifecycle management in the attach/detach
entry points of the volume manager for FC volumes (when fabric
zoning is enabled). Zones are configured automatically as part
of the active zone set in the FC SAN to provide a more flexible
and secure way of controlling access. FC zone manager enables
SAN vendors to add support for pluggable implementations.

1. Create a temporary volume in the destination with a copy of the source
2. Wait for the copy to complete
3. Delete the source
4. Rename the temporary to the same name as the original

Add x-openstack-request-id to cinder responses
x-openstack-request-id is the common header name for request ID going forward.
Currently, only glance and neutron return this header. Using the request_id
middleware is a convenient way to ensure this header is in the response. We will
also be using the middleware to generate the request ID.
The ID will be generated by the middleware and is inserted into the request
environment. The current code generates the request ID in the constructor of
RequestConext; with this change, the ID is generated beforehand and passed in to
the RequestContext constructor. Not much different here: a request ID is
generated and is available for use in the handling of the request.
On the response end, the middleware is again used, this time to attach the
x-openstack-request-id header, using the value of the generated request ID. The
current code attaches the x-compute-request-id header.
This change is a necessary step toward logging the mapping of request IDs across
OpenStack services.
This patch updates both the HP 3PAR Fibre Channel
and HP 3PAR iSCSI block storage drivers so that they
can pass the driver certification tests. We also updated
the unit tests to use mock instead of mox.
These versions of the drivers require the new 3.0.0 hp3parclient,
which can be downloaded from the pypi repository:
https://pypi.python.org/pypi/hp3parclient
The new hp3parclient requires the 3.1.3 firmware on the HP 3PAR.

This commit adds a new versioned api to the backup driver base

rule here is that we backup all metadata from a set of db tables
and can then be selective about what we restore.

to backup volume metadata (including glance metadata) thus
supporting restoring volumes as bootable.
It is expected that the other backup driver implementations will
follow suit and adopt this approach.

Check type argument on create from source and snap
Currently the create from snap and create from source
options will set the volume-type when specified in the
create call.
This is actually wrong, because clone and create from snap
MUST be performed on the same backend as the parent volume. The
result is that if the specified type doesn't match the specs for
it's parent, and actually needs to be on a different backend
the new volume will "appear" to have the correct type, but it's
actually invalid.
The --volume-type argument should be rejected when --source-volid
or --snapshot-id are used, and the parent type-id just picked up
and used. Then the user can retype if desired.
Auto failing this strictly causes backward compatability issues though
so we'll just check for a mismatch and raise an exception in that case.
This way if the user knows what they're doing and they're explicit
in the command we still allow it and things are fine.
