rootless: use a pause process
use a pause process to keep the user and mount namespace alive. The pause process is created immediately on reload, and all successive Podman processes will refer to it for joining the user&mount namespace. This solves all the race conditions we had on joining the correct namespaces using the conmon processes. As a fallback if the join fails for any reason (e.g. the pause process was killed), then we try to join the running containers as we were doing before.
