Three simple options shared among podman-create, exec, run.
I mostly went with the podman-run versions. For --tty, this
means that create and exec get the long stdout/stderr note.
(The example, though, remains only in podman-run). For -i,
mostly boldspace changes.
For --preserve-fds, podman-exec now has the "not with remote"
note (which it didn't until now)
