Clean up and rename conf_ns_open() conf_ns_open() opens file descriptors for the namespaces pasta needs, but it doesnt really have anything to do with configuration any more. For better clarity, move it to pasta.c and rename it pasta_open_ns(). This makes the symmetry between it and pasta_start_ns() more clear, since these represent the two basic ways that pasta can operate, either attaching to an existing namespace/process or spawning a new one. Since its no longer validating options, the errors it could return shouldn't cause a usage message. Just exit directly with an error instead.

Allow pasta to take a command to execute When not given an existing PID or network namspace to attach to, pasta spawns a shell. Most commands which can spawn a shell in an altered environment can also run other commands in that same environment, which can be useful in automation. Allow pasta to do the same thing; it can be given an arbitrary command to run in the network and user namespace which pasta creates. If neither a command nor an existing PID or netns to attach to is given, continue to spawn a default shell, as before.

pasta: By default, quit if filesystem-bound net namespace goes away This should be convenient for users managing filesystem-bound network namespaces: monitor the base directory of the namespace and exit if the namespace given as PATH or NAME target is deleted. We can't add an inotify watch directly on the namespace directory, that won't work with nsfs. Add an option to disable this behaviour, --no-netns-quit.
