This uses nginx' server-side includes, so each domain configured by
`__jitsi_meet_domain` can have its own customisation.
Note that the file customisation file must exist for each domain,
`__jitsi_meet_domain` takes care of that already.

with this, admins can take advantage of e.g. matomo to have some usage
statistics.
The parameter defaults to `disabled: true`, which is the most privacy-friendly!

This is done with slight adaptations from the official guide at
https://jitsi.github.io/handbook/docs/devops-guide/secure-domain
Amongst other changes, we rely on Prosody's configuration parser only overwriting the parts of a VirtualHost that are explicitly specified in "later appearing" (lexicographically speaking) files.
This allows us to let Jitsi manage the main config file and adding the few customisations on top of it.
We also use the Plaintext authenticator as this is enough atm and is the easiest to manage in an idempotent fashion; support for other authentication mechanisms is possible, see Prosody's documentation for that.
