Currently the getFields function doesn't take context as argument — this is the case because each form class is instantiated only once — so only one Form instance for login form, another one for forgot password form, etc.

This task is about changing that, so a new form instance is created upon every request — we probably have to change the .mount method to be static, and create an instance of the form for each request.

This way we could have a more dynamic behavior, where some users for example don't see certain fields or the fields for those users aren't required.
