UID/GID mapping with userns can be arbitrarily complex. Let's break this down to a single admin-friendly parameter: let's expose the UID/GID shift of a container via a new bus call for each container, and let's show this as part of "machinectl status" if it is not 0. This should work for pretty much all real-life full OS container setups (i.e. the stuff machined is suppose to be useful for). For everything else we generate a clean error, clarifying that we can't expose the mapping.
