Title: adding percona-heartbeat check

Hello,

This adds a plugin which allows users to monitor slave replication lag via percona pt-heartbeat which is provided by the [percona toolkit](http://www.percona.com/software/percona-toolkit).

this blog better explains why pt-heartbeat is better than mysql's `Seconds_Behind_Master`: http://www.metaltoad.com/blog/monitoring-mysql-replication
