Subject: BREAKING: Allow !include in config file

This changes semantics of these options:

  - key
  - oauth2.<provider>.client_secret

They are no longer files, but strings.  To read content
from files, use !include.  The point of being files or
read from files is to segregate secrets from non-sensitive
easily discoverable settings.  With !include it is much
more simple and flexible.
