The commit queue should not be stuck regardless of the state of the tests or host issues.

Generate a list of pain points and paths forward for each one as part of this ticket.

Notes from Slack

• OOM unittests caused the agent to be killed, which caused the task to restart
• 2 commit queue versions running concurrently, not 3
• lint running on rhel80-small, not the dedicated CQ variant

Solution spaces:

• More timely reverts
• Monitor runtime
• Bump min host count for the commit queue variant
• More validation pre-commit queue
