Bug Description

Hi, I think we should leverage lock-free SHOW SLAVE STATUS as documented:

http://www.percona.com/doc/percona-server/5.6/reliability/show_slave_status_nolock.html

SHOW SLAVE STATUS NOLOCK

I do not know if this will cause an issue with MySQL Community Edition, Enterprise Edition, or MariaDB, so perhaps will have to do conditional based on detected server version?

This should apply to Nagios pmp-check-mysql-replication-delay and to Cacti graphs.
