Verify that 'ctdb statistics' works as expected.

This is pretty superficial and could do more validation.

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 statistics' on a node, and verify that the output is
   valid.
3. Repeat the command with the '-n all' option and verify that the
   output is valid.

Expected results:

* 'ctdb statistics' shows valid output on all the nodes.
