      This is a clone of issue OCPBUGS-12150. The following is the description of the original issue:

      Description of problem:

      As outlined here (https://docs.openshift.com/container-platform/4.12/scalability_and_performance/recommended-host-practices.html#etcd-defrag_recommended-host-practices) it is generally a good process to defragment etcd. Today, hosted clusters on Hypershift do not have automatic defragmentation enabled. This may lead to increased etcd sizes and poor performance.

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

      MC OCP: 4.12.11
HC OCP: 4.12.12

      How reproducible:

      100%

      Steps to Reproduce:

      1. Deploy cluster
2. Watch etcd for signs of defragmentation
3.

      Actual results:

      etcd defragmention is not done

      Expected results:

      etcd automatically defragments
