Containerize Manila Share for HA

This service allows configuring and deploying manila-share
containers in a HA overcloud managed by pacemaker.

The containers are managed and run by pacemaker. Pacemaker runs the
standard Kolla image but overrides the initial command so that
it explicitely calls manila-share. This way, we shield ourselves
from any unexpected future change in Kolla.
This container needs to use the 'docker_config' section to invoke
puppet (as opposed to 'docker_puppet_tasks'), because due to the HA
composability each resource creation needs to happen on the bootstrap
node of that service and 'docker_puppet_tasks' will only run on the
controller/primary role.

Based on work done in fdb233e64e3d78014dd7e351abfed5aec5035866
