More threads can lead to a problem if a luci-app makes a fork
(e.g. for executing a command). Parallelism is still achieved
by using `processes = 3`.
Make the log more verbose by filtering only standard messages
for start/stop/reload out (leaving one line each).

Provide the minimal applications and plugins for: cgi, filelog, syslog and
python3. More plugins can be added if needed by other packages. Autostart
uwsgi in emperor mode loading vassals on demand.

For now, include luci-support (maybe it will be moved to another package),
which uses the syslog plugin by default.
