Add overview matrix to monitor home page

[DomGarguilo]

This PR replaces the two tables on the monitor home/overview page with a single matrix showing the counts of servers on each resource group with color highlighting problems. This PR also adds counts to the Servers navbar dropdown menu list.

Normal:

With a tserver and sserver killed:

With the GC killed (metrics not enabled so all other statuses are WARN):

Looks really good. Two questions:

1. Do you think we still need the resource group filter? I'm thinking no, but interested in hearing opinions.
2. Do you think you can get the dropdown menu icons to match the ones in the table (putting the counts inside the bubble)?

I don't have a strong opinion on this. Seems like it could probably be removed if nobody has any objections.

2. Do you think you can get the dropdown menu icons to match the ones in the table (putting the counts inside the bubble)?

I thought about this and tried it out but decided against it because I didn't want to tie the status LED too closely to the counts since there are other things that factor into the status for that server. I thought it would be confusing to have a full X/X count but have it be WARN color.

After some discussion more ideas surfaced:

1. remove the colors from the Totals row and columns (going to try this first) OR roll up the "most severe" color in that row and col to that total pill count
2. The title "Deployment Breakdown" can be removed
3. The resource group regex can be removed
