[Breaking changes]

We need a CreateAccount Sequence to allow Account Creation directly by users :

• This sequence must be public without authenticated context required
• It should called automatically a sequence that send an email to confirm account ( ConfirmAccount Sequence)

We need a ConfirmAccount Sequence that send a confirmation email to new user

• Confirmation email will be sent with a password reset key
• If password reset key is valid, then user will be marked as confirmed and be able to login

We need to change behavior of AddUser Sequence :

• This sequence should have a askForPasswordReset variable
• If called with askForPasswordReset to false, it should now mark users as confirmed since its creation has been done by an admin
• If called with askForPasswordReset to true, it should still mark user as draft and send an email to reset password. Whereas the password has not been reset by the user it should not allow to login

We need to change behavior of SignIn Sequence :

• SignIn Sequence must now refuse to login non confirmed accounts and ask them to Confirm account
