common-ha: delete-node implementation

omnibus patch consisting of:
+ completed implemenation of delete-node         (BZ 1212823)
+ teardown leaves /var/lib/nfs symlink           (BZ 1210712)
+ setup copy config, teardown clean /etc/cluster (BZ 1212823)

setup for copy config, teardown clean /etc/cluster:
1. on one (primary) node in the cluster, run:
  `ssh-keygen -f /var/lib/glusterd/nfs/secret.pem`

  Press Enter twice to avoid passphrase.

2. deploy the pubkey ~root/.ssh/authorized keys on _all_ nodes, run:
  `ssh-copy-id -i /var/lib/glusterd/nfs/secret.pem.pub root@$node`

3. copy the keys to _all_ nodes in the cluster, run:
  `scp /var/lib/glusterd/nfs/secret.*  $node:/var/lib/glusterd/nfs/`
  N.B. this allows setup, teardown, etc., to be run on any node
