[arch-announce] Breaking changes for all users of `varnish`, which is renamed to `vinyl-cache`

The Varnish project has [renamed itself to Vinyl Cache][0]. We followed this rename with a [new `vinyl-cache` package][1]. This upgrade results in [breaking changes][2] and users are advised to study these changes and how it affects them before following the replacement. All references to "`varnish`" have been changed to "`vinyl`" in all binaries and directories. At minimum, users will have to: - rename `/etc/varnish` to `/etc/vinyl-cache` - rename `/var/lib/varnish` to `/var/lib/vinyl-cache` - fix up ownership of files inside `/var/lib/varnish` - user `varnish` becomes `vinyl` - group `varnish` becomes `vinyl` - user `varnishlog` becomes `vinyllog` - user `vcache` remains the same - disable the old `varnish.service` and `varnishncsa.service` systemd units - enable the new `vinyl-cache.service` and `vinylncsa.service` systemd units Meanwhile, the `varnish` package has been dropped from `[extra]`. We're not currently planning to maintain a new `varnish` package as it's a different upstream project.
