docker: fix more than one monitor deployment

There is no need to run the actions from
roles/ceph-mon/tasks/docker/create_configs.yml
on the first monitor only since the monitor deployment happens
**serially**.
Moreover with Vagrant it's useful to allow the auto creation of the
cluster fsid, so enabling the option. If this is not desired you can
still set `fsid: 9c9c0448-0551-401d-b55b-e5b3a42bae42` for example.
