This is to allow broader support for proxies. In particular, this allows
support with Traefik.
This patch also includes some examples of configuration with Traefik.
Before this fix an anonymous user was not able to access a resource
that were configured with a bypass policy. This was due to a useless
check of the userid in the auth session. Moreover, in the case of an
anonymous user, we should not check the inactivity period since there
is no session.
Also refactor /verify endpoint for better testability and add tests
in a new suite.
Client and server now have their own tsconfig so that the transpilation is only
done on the part that is being modified.
It also allows faster transpilation since tests are now excluded from tsconfig.
They are compiled by ts-node during unit tests execution.
