Add OIDC support (#39)

* Update readme

* First try in oidc implementation

* Add secrets

* Add connection to fs auth provider, redirect not tested

* Working prototype

This commit implements the oidc compatibility with the caveat of having
every subsite under the app path. For that, there is also a redirection
handler to redirect the home page to the app home page.

* Small cleanup

* Fix access even when logged in

* Update application-prod.properties

* Ignore login when in test env

* Fix reviews
