Drop most of the existing certificate handling, because we're effectively
duplicating functionality that NixOS offers for free with better
design, testing and maintainance than what we could provide downstream.
The remaining two options are to reference an
existing `security.acme.certs` configuration through
`mailserver.x509.useACMEHost` or to provide existing key material via
`mailserver.x509.certificateFile` and `mailserver.x509.privateKeyFile`.
Support for automatic creation of self-signed certificates has been
removed, because it is undesirable in public mail setups.
The updated setup guide now displays the recommended configuration that
relies on the NixOS ACME module, but requires further customization to
select a suitable challenge.

instead of just smtp:// with STARTTLS.
Opted to call the flag --ssl and not --tls to keep it consistent with
the module option (mailserver.enableSubmissionSsl), dovecot internals
and smtplib in mail-check.py.
To generate the list of options, we need to generate and commit a rst
file to make all files available for ReadTheDoc.
An Hydra test ensures this generated file is up-to-date. If it is not
up-to-date, the error message explains the user how to generate it:
the user just needs to run `nix-shell --run generate-rst-options`.
When a local account address is forwarded, the mails were not locally
kept. This was due to the way lookup tables were internally managed.
Instead of using lists to represent Postfix lookup tables, we now use
attribute sets: they can then be easily merged.
A regression test for
https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/issues/
has been added: it sets a forward on a local address and ensure an
email sent to this address is locally kept.
