Bug Description
[Issue]
The percona-cluster only provides information to the hacluster charm to monitor a vip resource. This works well for node failures, but doesn't work well for certain application failures (e.g. mysql process dies). In the scenario where the mysql process dies, the VIP will not be transferred to another node in the cluster which can service requests. This results in a loss of access scenario.
[Steps to Recreate]
1. Deploy a percona-cluster with 3 nodes and pair with hacluster charm.
2. Stop the mysql processes on the node with the VIP
3. Observe VIP does not move to a host which can service the request.

There some really good information in [0] which has some information on percona resource agents etc that we may want to spend some time investigating whether or not it makes sense for these charms.
