auth_token Invalid option in 0.70.0.dev0

I get this error after upgrading to the latest version.  I had it working in 0.68.0.dev0.  

Invalid config for [konnected]: [auth_token] is an invalid option for [konnected]. Check: konnected->konnected->auth_token. 

answered my own question from the pull request:

Konnected users who are beta testing this: I've changed the auth_token configuration variable to access_token to be consistent with other similar HASS configs and to reuse an existing constant string. I'm updating the documentation accordingly.
