Ed Santiago 56039cffd7 Refactor common options in man pages 
podman-create and -run have many options in common. To date,
these are copy-pasted and haphazardly maintained.

Solution: add an include mechanism, '@@option foo', such
that multiple md source files can fetch from one common file.

This is a Phase One commit, a very small subset of what's
possible. Purpose of this commit is ease of review. If this
passes review, much more (trickier stuff) will be forthcoming.

--sdnotify=container | conmon | ignore

Determines how to use the NOTIFY_SOCKET, as passed with systemd and Type=notify.

Default is container, which means allow the OCI runtime to proxy the socket into the container to receive ready notification. Podman will set the MAINPID to conmon's pid. The conmon option sets MAINPID to conmon's pid, and sends READY when the container has started. The socket is never passed to the runtime or the container. The ignore option removes NOTIFY_SOCKET from the environment for itself and child processes, for the case where some other process above Podman uses NOTIFY_SOCKET and Podman should not use it.
