Compared to PID1 where systemd-oomd has to be the client to PID1 because PID1 is a more privileged process than systemd-oomd, systemd-oomd is the more privileged process compared to a user manager so we have user managers be the client whereas systemd-oomd is now the server. The same varlink protocol is used between user managers and systemd-oomd to deliver ManagedOOM property updates. systemd-oomd now sets up a varlink server that user managers connect to to send ManagedOOM property updates. We also add extra validation to make sure that non-root senders don't send updates for cgroups they don't own. The integration test was extended to repeat the chill/bloat test using a user manager instead of PID1.
