Verify that 'ctdb listnodes' shows the list of nodes in a ctdb cluster.

Prerequisites:

* An active CTDB cluster with at least 2 active nodes.

Steps:

1. Verify that the status on all of the ctdb nodes is 'OK'.
2. Run 'ctdb listnodes' on all the nodes of the cluster.
3. Verify that one all the nodes the command displays a list of
