Verify the operation of 'ctdb attach' command.
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. Shut down one of the nodes
3. Attach test databases
4. Start shutdown node
5. Verify that the databases are attached.
6. Restart one of the nodes
7. Verify that the databses are attached.
Expected results:
* Command 'ctdb attach' command successfully attaches databases.
