Remove reForis login page
There will be the new separated login instead of reForis current login page. It closes reforis#355 (closed).
This MR:
- removes the functionality for an old reforis login
- change the logout method
- change the way of redirect after the session is expired
To run this MR, you need to deploy it with this reforis and this turris-auth.
