rbd: provide host-path for rbd-nbd logging

Browse Source 
Problem:
--------
1. rbd-nbd by default logs to /var/log/ceph/ceph-client.admin.log,
Unfortunately, container doesn't have /var/log/ceph directory hence
rbd-nbd is not logging now.
2. Rbd-nbd logs are not persistent across nodeplugin restarts.

Solution:
--------
Provide a host path so that log directory is made available, and the
logs persist on the hostnode across container restarts.
