Purpose
=======
Allow portal users to deactivate their accounts from the portal view.
After the deactivation, they are redirected to the login page, so
they can verify that they can not longer login with their credentials.
We first archived the record and remove sensitive information (password,
login, so he can not log in again with the same credentials).
After the deactivation, we blacklist the email and the phone of the
user, so we are sure that we never send him again email / SMS.
Then, we create a <res.users.deletion> to delete the user and the
partner in a CRON because this operation can be heavy (write_uid,
create_uid field on all models).
