pacemaker: Discarding cib_apply_diff message (<number>) from <server>: not in our membership

[Chris J Arges]

[Impact]

 * Using 12.04 version of pacemaker in a VMWare enviornment will occasionally not sync on reboot.
 * The error message "warning: cib_peer_callback: DDiscarding cib_apply_diff message (<number>) from <server>: not in our membership" is present in log files.
 * It is expected the pacemaker syncs properly on reboot.

[Test Case]

 * Run 12.04 pacemaker in a VMWare environment and reboot multiple times.
 * This blog post has a decent write up on what happens: http://www.tomas.cat/blog/en/troubleshooting-pacemaker-discarding-cibapplydiff-message-xxx-server2-not-our-membership

[Regression Potential]

 * The patch https://github.com/ClusterLabs/pacemaker/commit/03f6105592281901cc10550b8ad19af4beb5f72f has been identified as solving the issue. This patch is present in pacemake-1.1.7 and beyond. This this code is in the quantal version and beyond.

Chris, 12.04 has 1.1.6-2ubuntu3.1, so 1.1.6-2ubuntu2.3 can't even be uploaded.

Chris, made a typo he actually uploaded 3.2 to the -proposed queue.
