The command 'ctdb wipedb' is used to clear a database across the whole
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. Create a persistent test database
3. Add some records to node #0 and node #1
4. Perform wipedb on node #0 and verify the database is empty on both node 0 and 1

Expected results:

* An empty database will result
