Which issue this PR addresses:

Fixes https://issues.redhat.com/browse/ARO-1933

What this PR does / why we need it:

This PR is needed to allow for ARO SREs to send signals when cluster maintenance is being performed. Those signals will go to resource health check so customers get notified.

Code changes:

  1. Add maintenance states to CosmosDB cluster document
  2. Add maintenance state admin update task
  3. Emit metric via monitoring stack. Metric lists the cluster's maintenance state.

More info can be found here: https://msazure.visualstudio.com/AzureRedHatOpenShift/_wiki/wikis/AzureRedHatOpenShift.wiki/508199/Maintenance-Signals

Test plan for issue:

  • Unit tests
  • Tested in INT

Is there any documentation that needs to be updated for this PR?

Code review:

  1. Review design with ben/rogerio
  2. Investigate using middleware so you don't have to modify a bunch of ARO-SRE scripts
