Verify that  'ctdb getdbmap' operates as expected.

This test creates some test databases using 'ctdb attach'.

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. Get the database on using 'ctdb getdbmap'.
3. Verify that the output is valid.

Expected results:

* 'ctdb getdbmap' shows a valid listing of databases.
