Subject: [PATCH] Add environment variable to set email client

The 'client' setting control what the Smtp client sends as EHLO/HELO
message to the smtp-server, this change allows the behaviour to be
controlled via environment variable instead of having to mount your
own email.php file.

This change requires that
https://github.com/passbolt/passbolt_api/pull/209 is merged.
