Verify that CIFS connections are monitored and that CIFS tickles are sent.
We create a connection to the CIFS server on a node and confirm that
this connection is registered by CTDB. Then disable the relevant CIFS
server node and ensure that the takeover node sends an appropriate
reset packet.
Prerequisites:
* An active CTDB cluster with at least 2 nodes with public addresses.
* Test must be run on a real or virtual cluster rather than against
local daemons.
* Test must not be run from a cluster node.
* Clustered Samba must be listening on TCP port 445.
Expected results:
* CTDB should correctly record the connection and the takeover node
should send a reset packet.
