Goal

Note: This is an internal improvement. There are no user-facing deliverables.

There are a few areas to cover for Disaster Recovery (DR):

Finish rewriting the existing DR Bash scripts in Go
Add guardrails to code that will not allow the customer to cause additional damage to cluster during disaster recovery.
Cleanup technical debt from MCO repo and installer.

Why is this important?

When a cluster has an event that for example results in quorum loss this is a very stressful situation. If we can provide a very clean solution to this event with well thought out tools the admin will be pleased.

So we don't run into customer situations like this
