Usage messages: show possible option values
...in a consistent manner: ("a"|"b"|"c")
This makes it possible (and easy) for zsh completion to
pick those out of the --help messages and offer them
as values when user hits TAB.
I chose this format because it's an already-existing
convention in cmd/podman/common.go.
Also: removed two duplicate "default: x" messages (Cobra
displays those automatically where a non-null default
is specified).
