 TypeError: a bytes-like object is required, not 'str'

      Fix required in policylib to change from 

      return {"KV": {"Verb": verb, "Key": key, "Value": base64.b64encode(value)}}

      to

      return {"KV": {"Verb": verb, "Key": key, "Value": base64.b64encode(value.encode("utf8")).decode("utf8")}}

      value.encode("utf8") <- convert value (a string) to a byte array
      base64.b64encode(str).decode("utf8") <- convert the byte array returned by b64encode into a string

       

      New lib to be pushed into Pypi, k8s plugin requirement should be updated to fetch revised plugin followed by CM container update
