Title: Support Arbiters

In order to get this check working against Arbiter instances we need to ignore :replication_lag on Arbiter instances as they do not support replication.

Hopefully this change supports triggers. I can't remember off hand what happens when a trigger is set up and an instance does not report the metric.
