      Version of components:

      opentelemetry-operator.v0.102.0-2

      OpenShift version  4.16.1

      Description of the problem:
      When a OpenTelemetry Collector instance is created on OpenShift version 4.16, we see a perpetual creation of secrets in the namespace. Around 15-20 secrets are created per second. We need to get this fixed as soon as possible as it can overwhelm the API server causing the cluster to be instable.

      Steps to reproduce the issue:

      • Deploy a OpenShift 4.16 cluster.
      • Create a OpenTelemetry collector instance.
      • Check the OpenTelemetry Collector instance namespace for the secrets.
      • Notice that the secrets are continuously being generated. 

      Additional details:
      The issue occurs on OpenShift version 4.16 only.
