Run the ctdb_fetch test and sanity check the output.
This doesn't test for performance regressions or similarly anything
useful. Only vague sanity checking of results is done.
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_fetch on all nodes with default options.
3. Ensure that the number of +ve and -ive messages are within 1% of
each other.
4. Ensure that the number of messages per second is greater than 10.
Expected results:
* ctdb_fetch runs without error and prints reasonable results.
