The galera cluster rely on WSREP for cluster consistency. While the default MySQL monitor will allow us to know when the database node is minimally functional it does not provide the ability to query the node state allowing loadbalancers, operators, and deployers to know a node is healthy prior to being allowed to accept connections. This change implements the checkcluster script as provided by the fine folks at Percona. The implementation of this check follows the guild-lines noted here [0]. With this in-place, we'll be able to convert our haproxy check for the galera cluster nodes to use an HTTP check on port 9200 instead of the default MySQL login which will provide for a more robust and fault tolerant cluster.
