Separate monitoring and move to 60s interval
Removes the dependency of the monitoring subsystem from the node keepalives, and runs them at a 60s interval to avoid excessive backups if a plugin takes too long. Adds its own logs and related items as required. Finally adds a new required argument to the run() of plugins, the coordinator state, which can be used by a plugin to determine actions based on whether the node is a primary, secondary, or non-coordinator.
