study: run the AIOpsLab audit against a proposed fix that records the deployed workloads

[TheDeadcoder]

Adds workload_check.patch, a proposed fix for AIOpsLab's mitigation verifiers, and lets the audit run against it.

• With the patch, a pod without container statuses counts as unhealthy unless it has succeeded.
• AIOpsLab records the application's Deployments and StatefulSets after deploy. eval() then fails if one of them
  no longer exists or is scaled to zero.
• The four problems with their own pod checks use the shared one. The Kafka problem also requires its feature flag
  to be off.
• The runner takes --runs, so the patched runs go to runs-patched/ with their own ledger. It stops when an
  episode saves no result.
• The README has the predictions for the patched runs, fixed before they ran.

The patch makes the same changes as the upstream proposal, microsoft/AIOpsLab#209. The results come in a separate PR.
