func_documentation_string: Creates k8s Service and Job for the Teraslice Execution Controller
  (formerly slicer).  This currently works by creating a service with a
  hostname that contains the exId in it listening on a well known port.
  The hostname and port are used later by the workers to contact this
  Execution Controller.
