Verify that a node's public IP address can be deleted using 'ctdb deleteip'.
This test does not do any network level checks that the IP address is
no longer reachable but simply trusts 'ctdb ip' that the address has
been deleted.
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. Use 'ctdb ip' on one of the nodes to list the IP addresses being
served.
3. Delete one public IP address being be served by the node, using
'ctdb delip'.
4. Verify that the delete IP address is no longer listed using the
all_ips_on_node helper function.
Expected results:
* 'ctdb delip' removes an IP address from the list of public IP
addresses being served by a node.
