When calling send on SMS, sent SMS are unlinked. If a ``delete_all`` parameter
is true, failed SMS are also unlinked.
In this commit we allow to control that behavior with two boolean, one for
sent SMS and one for failed SMS. This allows to ask to keep sent SMS and
update their status accordingly.
More control is necessary notably to enable IAP feedback on sent SMS as
an error could happen after considering it as sent. Some flows will have to
be updated to decide whether this status is necessary and if SMS are kept.
This commit prepares ground for that feature by already improving methods
and API.
