Add a "Database Cluster Status" console in Config

Summary: Ref T4571. The configuration option still doesn't do anything, but add a status panel for basic setup monitoring.

Test Plan:
Here's what a good version looks like:

{F1212291}

Also faked most of the errors it can detect and got helpful diagnostic messages like this:

{F1212292}
