Ed Santiago 9934507d74 Command-line input validation: reject unused args ...

Several podman commands accept no subcommands. Some
of those were not actually checking, though, which
could lead to user confusion. Added validation where
missing; and, refactored to minimize duplication.

(Side note: I decided against using cobra.NoArgs
because its error message, "unknown command",
misleadingly implies that there are known ones).

Also added validation to varlink
