config: support multi-value inbox.*.*url

Since the beginning of this project, we've implicitly supported
inboxes with multiple URLs by relying on the Host: header sent
by the client ($env->{HTTP_HOST}).

We now offer the option to explicitly configure multiple URLs for
every inbox along with the ability to do a best-effort match for
matching hostnames.
