Option Idea: System Health not affected by Downtimes

[fatdollar]

This could be an option that is configurable but it would be nice if a host or service that has been marked as with a downtime does not show up as a "problem" and doesn't affect the overall Health Check.

In my scenario, I have many hosts that are seasonal and will be down for months. Rather than constantly disabling and reenabling them it would be great to just mark them as down for a specific time and then have checks automatically begin when the downtime is over but during that time. I'd like to just completely forget about it and not have it listed as an overall problem. This way my higher ups don't think we have network issues when we do not.
