devstack plugin.sh does not support rethinkdb drivers

[Steve Kipp]

When running devstack on a single node controller, using the configuration specified in:
https://github.com/openstack/dragonflow/blob/master/doc/source/single-node-conf/rethinkDB_local_controller.conf

You will receive an error:
"No database driver is set for Dragonflow."

This error is thrown in
https://github.com/openstack/dragonflow/blob/master/devstack/plugin.sh
on L97-99

In the lines above L72-94 it looks like rethinkDB is absent from the available drivers to be sourced.

We planned to support RethinkDB, but it has not been done yet.

At the time it was working, but it need to be updated/merge to the latest db Api abstraction changes, ping me if you need any help
