Refactor the systemd service definition for the haproxy reverse proxy,
using the upstream systemd service definition. This allows the service
to be reloaded on changes, preserving existing server state, and adds
some hardening options.
it does happen that `dnscrypt-proxy` exit when it is unable to
synchronise its resolvers metadata on startup. this can happen due
to network connectivity issues for example. not restarting it automatically
means no dns resolution will work until a manual restart is performed.
Favor the configuration in "configFile" over "config" to allow
"configFile" to override "config" without a system rebuild.
Add a "persistentKeys" option to generate keys and addresses that
persist across service restarts. This is useful for self-configuring
boot media.
Add extraConfig option for the muc submodule.
Also move the global extraConfig before all components and
virtualhosts, because the manual states:
The configuration is divided into two parts. The first part is known as
the "global" section. All settings here apply to the whole server, and
are the default for all virtual hosts.
The second half of the file is a series of VirtualHost and Component
definitions. Settings under each VirtualHost or Component line apply
only to that host.
Before, if at least one muc was defined, or uploadHttp enabled, the
global extraConfig would end up after "muc" or "http_upload" component
making it apply to that component only and not globally.
We add a Prosody entry to the NixOS manual showing how to setup a
basic XEP-0423 compliant Prosody service. This example also showcase
how to generate the associated ACME certificates.
Note: The <programlisting> body might look poorly indented, but trust
me, it's necessary. If we try to increase their indentation level, the
HTML output will end up containing a lot of unecesseray heading spaces
breaking the formatting...
The output file is found and handled by thelounge itself [1], leaving
the user free to override THELOUNGE_HOME in the environment if they
choose, but having a sensible default to make `thelounge` generally
usable in most cases.
This solution follows discussion on #70318.

We are leveraging the systemd sandboxing features to prevent the
service accessing locations it shouldn't do. Most notably, we are here
preventing the prosody service from accessing /home and providing it
with a private /dev and /tmp.
Please consult man systemd.exec for further informations.
