> Aggregate alert does not show status properly at Maintenance Mode change.
> Steps to reproduce:
> Install a cluster that has HBase with one regionserver installed.
> Scenario 1:
> 1. Turn On Maintenance Mode on the RegionServer or on the RegionServer host 
> or on the HBase service.
> 2. Stop the RegionServer after that.
> 3. No red alerts will show as expected.
>    Percent RegionServers Available - OK affected: [0], total: [1]
> 4. Now Turn Off Maintenance Mode, still keep the RegionServer down.
>    But Percent RegionServers Available alert will still show "OK" - "CRIT" is 
> expected.
> Scenario 2:
> 1) Stop the RegionServer - Red alert will show as expected.
>    Percent RegionServers Available - CRIT affected: [1], total: [1]
> 2) Now Turn On Maintenance Mode - For RegionServer status, Red alert will be 
> gone as expected.
>    But Percent RegionServers Available alert will still show "CRIT" - "OK" is 
> expected.
