Driver plugin openstack is not found

[Chiawei Xie]

OS: ubuntu 16.04
version: 6.0.0
openstack sdk version: 0.17.2
Install method: pip install senlin==6.0.0

Used openstack cluster command, got some errre message:
"Driver plugin openstack is not found.", "type": "InvalidPlugin"

And check senlin-api ERROR log:

ERROR stevedore.extension
Could not load 'container.dockerinc.docker-1.0': 'module' object has no attribute 'enable_logging'

ERROR stevedore.extension
Could not load 'openstack': 'module' object has no attribute 'enable_logging'

I have seen this issue before when switching between versions of Senlin in git. When I encountered this issue the senlin/drivers/ folder had an empty folder called openstack in it.

I deleted this folder and everything returned to normal.

I also got this error after I had reinstalled openstacksdk while senlin engine was running.

Reinstalling senlin engine and restarting it fixed it.
