Deprecate volume create --project and --user options

Cinder's volume create API does not support overriding the project_id and
user_id, and it silently igores those API inputs. Cinder always uses the
project and user info in the keystone identity associated with the API
request.

If a user specifies the --project or --user option, the volume create is
aborted and a CommandError exception is raised. This prevents a volume
from being created, but without the desired project/user values.

A user wishing to specify alternate values can still do so using identity
overrides (e.g. --os-username, --os-project-id).
