provisioning: /var/log/contrail mount has to be per container

[Senthilnathan Murugappan]

all the containers(controller, analytics, analyticsdb) /var/log/contrail is a mount of hosts /var/log/contrail dir and the uid/gid of the dir gets set to the contrail user of the first container that mounts it and hence the other containers observe permission denied issue when trying to create the logfile.
Each container needs to have a separate mount points.

WORKAROUND:
===========

Workaround is to set the following in the playbook inventory:

contrail_controller_log_volumes=['/var/log/contrail/controller:/var/log/contrail', '/var/log/zookeeper:/var/log/zookeeper']
contrail_analytics_log_volumes=['/var/log/contrail/analytics:/var/log/contrail']
contrail_analyticsdb_log_volumes=['/var/log/contrail/analyticsdb:/var/log/contrail']

OR if SM is used to provision, include this in the cluster.json:

                "provision": {
                    "contrail_4": {
                        "contrail_controller_log_volumes": ["/var/log/contrail/controller:/var/log/contrail",
                            "/var/log/zookeeper:/var/log/zookeeper"],
                        "contrail_analytics_log_volumes": ["/var/log/contrail/analytics:/var/log/contrail"],
                        "contrail_analyticsdb_log_volumes":["/var/log/contrail/analyticsdb:/var/log/contrail"]
                    }
                }
