      Description of problem:

      We observe cluster-image-registry-operator pods using large number of inotify instances running into /proc/sys/fs/inotify/max_user_instances limit eventually.

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

      openshift-v4.19.0

Since the only cluster-image-registry-operator that is not leaking inotify instances is the one from an 4.18.1 cluster,  the problem seems to be introduced in 4.19

      How reproducible:

       100% (in ARO HCP environment)

      Steps to Reproduce:

          1. Install ARO HCP service infrastructure and provision few clusters
    2. Notice issues with image-registry because of too many open files

      Actual results:

      Expected results:
