As discussed in https://review.openstack.org/#/c/36352/ for each

this was for an old way of calling commands that are is no longer
used.
Also removed openstackclient/common/command.py

We use the V1 API for `create` since it does not
yet exist in the V2 API in glanceclient.
For blueprint glance-client.
