      —
      Description of problem:

      HyperShift-managed components use the default RevisionHistoryLimit of 10. This significantly impacts etcd load and scalability on the management cluster.

      Version-Release number of selected component (if applicable):

      4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16

      How reproducible:

      100% (may vary depending on resource availablility on management cluster)

      Steps to Reproduce:

          1. Create 375+ HostedCluster
    2. Observe etcd performance on management cluster
    3.

      Actual results:

      etcd hitting storage space limits

      Expected results:

      Able to manage HyperShift control planes at scale (375+ HostedClusters)
