Make it easy to subclass Saml2Controller

[tentus]

There is a feature in the aacotroneo/laravel-saml2 library which allows users to extend the controller without having to redefine all the routes by defining a saml2_controller config value, which you can see here.

It's very simple to implement, and I was able to duplicate the functionality with minimal tweaks to rectify stylistic differences between the two repos. My intent here is to make it easier for users of the aacotroneo lib to switch over to this one (and by users I mean me, specifically, but I'm sure other people could also use this feature).

I also bumped into this trying to add login_hint to my login calls

I'm looking forward to this feature. Can you merge it please ?
