      This is a clone of issue OCPBUGS-38573. The following is the description of the original issue:
      —
      Description of problem:

      While working on the readiness probes we have discovered that the single member health check always allocates a new client. 

Since this is an expensive operation, we can make use of the pooled client (that already has a connection open) and change the endpoints for a brief period of time to the single member we want to check.

This should reduce CEO's and etcd CPU consumption.

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

      any supported version

      How reproducible:

      always, but technical detail

      Steps to Reproduce:

       na

      Actual results:

      CEO creates a new etcd client when it is checking a single member health

      Expected results:

      CEO should use the existing pooled client to check for single member health
