This adds support for the client credential flow oauth method which
requires some special handling in onedrive:
- Special scopes are required
- The tenant is required
- The tenant needs to be used in the oauth URLs
This also:
- refactors the oauth config creation so it isn't duplicated
- defaults the drive_id to the previous one in the config
- updates the documentation

This commit reorganises the oauth code to use our own config struct
which has all the info for the normal oauth method and also the client
credentials flow method.
It updates all backends which use lib/oauthutil to use the new config
struct which shouldn't change any functionality.
It also adds code for dealing with the client credential flow config
which doesn't require the use of a browser and doesn't have or need a
refresh token.
