UPDATE_RECORD control should be able to create new records and update
existing records in a persistent database.

Prerequisites:

* An active CTDB cluster with at least one active node.

Steps:

1. Verify that the status on all of the ctdb nodes is 'OK'.
2. create a persistent test database
3, wipe the database to make sure it is empty
4, create a new record
5, update the record

Expected results:

* 4 created record found in the tdb
* 5 updated record found in the tdb
