* [FEATURE] Add TLS support.
Fixes#368.
* [FEATURE] Introduce OnError hook in suites.
This hook allows to perform actions following an erroneous suite
like displaying the logs of Authelia.
* Display Authelia logs of Standalone suite when tests fail.
* Fix Standalone suite.
* Apply suggestions from code review
* Rename ssl_key and ssl_cert into tls_key and tls_cert.
* Redirect to default URL after 1FA when default policy is one_factor.
User is now redirected to the default redirection URL after 1FA if
the default policy is set to one_factor and there is no target URL
or if the target URL is unsafe.
Also, if the default policy is set to one_factor and the user is already
authenticated, if she visits the login portal, the 'already authenticated'
view is displayed with a logout button.
This fixes#581.
* Update users.yml
* Fix permissions issue causing suite test failure
Providing a GA tracking ID allows administrators to analyze
how the portal is used by their users in large environments,
i.e., with many users.
This will make even more sense when we have users and admins
management interfaces.
