Add EMC Volume Driver in Cinder
Add support for EMC storage in the Cinder-Volume service.
This driver is based on the existing ISCSIDriver, with the ability to
create/delete and attach/detach volumes and create/delete snapshots, etc.
The Cinder Driver executes the volume operations by communicating with the
backend EMC storage. It uses a CIM client in python called PyWBEM to make
CIM operations over HTTP.
EMC CIM Object Manager (ECOM) is packaged with the SMI-S Provider. It is a
CIM server that allows CIM clients to make CIM operations over HTTP, using
SMI-S in the backend for EMC storage operations.
SMI-S Provider supports the SNIA Storage Management Initiative (SMI), an
ANSI standard for storage management. It supports VMAX/VMAXe and VNX
storage systems.
Commit cbcd340 changed from NamedTemporaryFile to mkstemp, but
mkstemp returns a file descripter, not a file object. We therefore
need to close the fd using os.close(). This was tested using
devstack.
The 3par driver, for both iSCSI and Fibre Channel,
that I will commit soon, needs the lockutils to ensure thread safety in
each of the driver entry points. The driver uses a single shared http
session for all of it's connections to the 3par drive array.
This is required for the driver because of the limitation on the
3par's WSAPI only supporting a very small number of open connections.
For example without this, the driver will have problems when 2 users try and
create a volume at the same time. I've discovered this in my threaded
stress test tool.
When a VHD created by Cinder using the iSCSI Target Server is deleted
manually, at the next startup the cinder-volume service terminates with an
exception.
This fix adds a check to verify if the disk exists.
Adds a new configuration option called lvm_mirrors. If this is
set to a value > 0, it will create the specified number of mirrors
when creating volumes. Note that lvm_mirrors + 2 pvs are required
in the volume group for lvm mirroring to work properly.

Make copy_to_volume a bit more useful.

Convert volume_type id from int to uuid.
This converts the volume_type id from int to uuid. In
addition, this also corrects an issue of deleting volume_types
by name. Even though the client/api is taking the id, it was
converting to the name of the volume_type for the db access.
We also want to continue enforcing that the name is unique on creation
so as to avoid any confusion and for clarity in Horizon. The api
has also been enhanced to allow you to specify the type by name
or by uuid.
This does NOT modify the things like the volume details display field
(currently shows the type 'name' not 'uuid'), these types of changes
will go in to V2 of the API.
