Giuseppe Scrivano 791d53a214 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.
