Add update password configuration

In this mr I added the possibility to set the update password required action. This is useful when we want to use this SPI with the built-in browser authentication and not with a custom workflow.

By the way, when an user wants to register its account after clicking on the email he will be asked to set his password on the start up of registration process.

Thanks for the addition. Looks good to me!
