Config drive support for ceph radosgw

Currently config drive can be stored in swift with keystone
authentication. This change allows ironic to store the config drive in
ceph radosgw and use radosgw authentication mechanism that is not
currently supported. It uses swift API compatibility for ceph radosgw.

New options:
    [deploy]/configdrive_use_object_store
    [deploy]/object_store_endpoint_type
Deprecations:
    [conductor]/configdrive_use_swift
        Replaced by: [deploy]/configdrive_use_object_store
    [glance]/temp_url_endpoint_type
        Replaced by: [deploy]/object_store_endpoint_type
