Change I9b2d140065390d94dda532c39777cf691775e21e has added masakari
commands to openstacksdk and those are available in openstacksdk
version 0.13.0. So the respective sdk resource proxy class implemented
in masakariclient is no longer required.
This patch fixes below:
- Removes the proxy class from masakariclient, and modifies to use the
proxy class implemented in openstacksdk.
