store, and switch back to the original user when deploying on a gcp cluster

here's how it looks when run locally:

$ hubploy --verbose deploy jupyter hub staging
INFO:hubploy.__main__:Namespace(command='deploy', debug=False, helm_debug=False, verbose=True, deployment='jupyter', chart='hub', environment='staging', namespace=None, set=None, set_string=None, version=None, timeout=None, force=False, atomic=False, cleanup_on_fail=False, dry_run=False, image_overrides=None)

<SNIP some output>

INFO:hubploy.auth:Attempting to authenticate with gcloud...
INFO:hubploy.auth:Saving current gcloud login
INFO:hubploy.auth:Current gcloud login: <my gcloud login address redacted>
INFO:hubploy.auth:Decrypting deployments/jupyter/secrets/gke-key.json

<SNIP more output>

i don't believe that i need to use this decorator... but i'm unsure and not an expert in this bit of python. :)
