added token auth method

[ttaeschn]

implements #3

Hey, thanks @ttaeschn for the PR!
Especially since I don't have time to work on this plugin at the moment...

Still, I would rather use another proeprty, having a token in the "authPath" variable is counter-intuitive. Maybe something like this:

if authToken is defined
  then use authToken
  else use authPath

WDYT?

Was this authToken feature implemented? Trying to use this in an environment with multiple namespaces and don't see how I can specify a namespace but a token might work.

not yet, I'll try to work on it today. your work will help.
