Allow to pass extra data when handling success authentication

[VincentLanglet]

Hi @chalasr,

I have a use case when I'd like to return an extra data in the response of the authentication, basically a user "state" (in context of SSO to tell if the user was created or already exists).

In my service I already do my work and then call

$this->authenticationSuccessHandler->handleAuthenticationSuccess($user)

manually.

Unfortunately I cannot pass aditionnal data this way. Listening the Events::AUTHENTICATION_SUCCESS event to modify the data is not a solution, since the listener won't have the information i want to add to the event data.

The best solution I see is, in the same way it's currently possible to pass a specific jwt, to allow passing extra data on the handleAuthenticationSuccess method.

I try to implement it ; WDYT ?

Failure seems unrelated.
