How reproducible:

100%

Steps to Reproduce:
1.
2.
3.

Actual results:

As the /var/log/ceilometer is not bind, we can't check logs of ceilometer central under /var/log/containers/ceilometer. Plus if we restart/kill ceilometer_agent_central then the logs will be lost.

Expected results:

/var/log/ceilometer should bind with host /var/log/containers/ceilometer like ceilometer_agent_notification does.
