Use replace() for Services instead of patch()

[seleznev]

k8s-handle uses patch() API call for Services because of historical reason (looks like kubectl didn't support replace for services some years ago) and can't delete labels/annotations from the Services:

2020-10-13 06:25:37 INFO:k8s_handle.k8s.provisioner:Service "test-service" already exists, replace it
2020-10-13 06:25:37 WARNING:k8s_handle.k8s.provisioner:
       ___
    .-'   `-.
   /  \   /  \\     Please pay attention to service annotations!
  .   o\ /o   .    The next annotation(s) missing in template:
  |___  ^  ___|    "test-annotation"
      |___|        They won\'t be deleted after service apply.
      |||||

I propose to start using replace() for Services because kubernetes client works well for now.
