Updated create_volume routine in the cloudstack.py file to support
ex_volume_type
## Updated create_volume routine in the cloudstack.py file to support
ex_volume_type
### Description
As part of the deployment of an internal cloud using CloudStack, we
discovered that
one cannot use the "DiskOffering" capability of CloudStack to select
volumes with
specific attributes. When reviewing the OpenStack portion of the library,
this is
supported using the ex_volume_type variable in the call to create_volume.
The CloudStack DiskOffering capability is required for this deployment, so
the create_volume
routing in cloudstack.py was updated to add this as an option using the
same variable name
as used for OpenStack.
When a DiskOffering is specified, the input size to create_volume is
over-riden by the
size of the DiskOffering, unless the DiskOffering size is customizable.
This was chosen
to minimize errors, as if someone calls create_volume with the
ex_volume_type option,
then it is likely that is what they want, even if the specified size is
different from the request.

Updated create_volume routine in the cloudstack.py file to support
"DiskOffering" selection using same variable name as for OpenStack
(ex_volume_type). This allows one to specify a specific volume type.
When ex_volume_type is specified, the size of the volume is defined
by that volume type, unless it is adjustable. Updated
tests to validate changes to create_volume.
