[bug#44800] [PATCH v2 0/3] publish: Add Avahi support.

[Mathieu Othacehe <othacehe@gnu.org>]

Hello,

Here's a v2 that now provides a complete chain. "guix publish" services that
are started with "--enable-avahi" will be discovered by the "guix-daemon" when
the "--use-local-publish" option is passed.

A new "guix discover" script is used to discover publish services in the
background. I have tested this setup by starting a guix-publish server in a
VM.

As suggested here:
https://guix.gnu.org/blog/2017/reproducible-builds-a-status-update/ the local
publish servers are prefixed to the substitute-url list, so that the daemon
will try to use substitute from the local network first, before falling back
to the CI build farm.

Thanks,

Mathieu
