The configfile "config" and "settings" attributes never change, and
therefore do not need to be stored in the subscription cache. They
can be significantly large, so this change can free up some memory
on low resource systems.

If Klipper is using systemd socket activation to generate its
unix socket the PID reported by PEERCRED will be 1, that of
systemd itself. Klipper now reports its process id in the
"info" endpoint, use that as a fallback to retreive service info.
