And when not possible, document why.
Note for the future: there is some repetition in some modules to
configure the correct value of the subdomain, which I happen to know
will line up correctly thanks to the nginx wrapper. A good way to
refactor this in the future would involve avoiding this repetition,
allowing use to query the correct domain in some way...
This is a requirement anyway for homeservers, and the `forceSSL` option
tried to create a redirect for non-SSL traffic, except the `listen`
option only provided SSL endpoints anyway, so this resulted in
additional rules in the nginx config looking like this:
```nginx
server {
server_name matrix.belanyi.fr ;
location /.well-known/acme-challenge {
root /var/lib/acme/acme-challenge;
auth_basic off;
}
location / {
return 301 https://$host$request_uri;
}
}
```
