BZ #1049121 -  Install a Highly Available ... Foreman (HA/mysql)

https://bugzilla.redhat.com/show_bug.cgi?id=1049121

The custom fact, $hamysql_active_node, did not behave as expected
during an initial puppet run if pcs was not yet installed: it would
return true rather than the expected false.  Also, if there were
"Failed actions" in the output of "pcs status", the fact would always
incorrectly return false.  Both of these issues are fixed.

Additionally, the primary HA/mysql puppet manifest, node.pp, as been
updated to work with the lastest puppet-pacemaker module.
