git-harry 4a860f715c Restart mysql when config changed
Currently mysql is only (re)started when creating a cluster, adding a
node or the service isn't running. This means changes to configuration
files are not used.

This commit moves the restart functionality to a handler and sets
notifies on the the appropriate tasks so that when the config is changes
mysql is restarted.

This commit modifies the galera play to run in serial so that only one
instance of mysql can be restarted at a time. This is to prevent the
possibility of them all being restarted in one go. An additional play
'Check galera cluster status' has been added, this makes an attempt to
check that the cluster is healthy before proceeding with any possible
config changes. The checks can be overridden by setting
'galera_ignore_cluster_state=true' when running the playbook.

A facts module has been added to gather information about the status of
the cluster for use by the galera-install playbook.
