allow heartbeat monitor's heartbeat intervals and # of missed heartbeat to be overrideable parameters on the monitor.
Heartbeat frequency and number of allowed missed heartbeats should be overridable parameters on the monitor so they can be managed using the override screen as well. This adds the benefit of knowing when they have been changed. Currently only the frequency can be changed, and that is per agent or by bulk via powershell and even that is not done through a normal override as other SCOM monitors. Number of allowed missed heartbeats is only a global change at the moment so you cannot change it at all. I would like the ability to do both.
