Allow redirection to original URL after account creation
When creating a new account, the origin URL is lost. The goal is to allow the user to be redirected back to his origin URL: header protected application, SAML SP, OIDC client,...
We need to store all informations from incoming URL in the persistent session (protected url, saml request,...) Then at the end of account creation, we need to resume the previous kinematic: redirect to protected url, saml request,... Also, we must consider coexistence with #1620
@guimard @maudoux @maxbes @clement_oudot : do you have some advice for integrating this feature properly, simalarly to what have been done in 2.0 to fix SAML / OIDC chaining? Do you think it can be included into 2.0.X, or should it be in 2.1?
