Docs: consistency between man / --help
New functionality in hack/man-page-checker: start cross- referencing the man page 'Synopsis' line against the output of 'podman foo --help'. This is part 1, flag/option consistency. Part 2 (arg consistency) is too big and will have to wait for later. flag/option consistency means: if 'podman foo --help' includes the string '[flags]' in the Usage message, make sure the man page includes '[*options*]' in its Synopsis line, and vice-versa. This found several inconsistencies, which I've fixed. While doing this I realized that Cobra automatically includes a 'Flags:' subsection in its --help output for all subcommands that have defined flags. This is great - it lets us cross-check against the usage synopsis, and make sure that '[flags]' is present or absent as needed, without fear of human screwups. If a flag-less subcommand ever gets extended with flags, but the developer forgets to add '[flags]' and remove DisableFlagsInUseLine, we now have a test that will catch that. (This, too, caught two instances which I fixed). I don't actually know if the new man-page-checker functionality will work in CI: I vaguely recall that it might run before 'make podman' does; and also vaguely recall that some steps were taken to remedy that.
