(#5552) Clean up subcommand handling inside puppet cert.

We now have a regular, testable mechanism for handling the legacy '--' version
of subcommands, as well as a modern bareword subcommand pattern.  This makes
it sensible to test command handling and avoid regressions.

We identified a few quirks in the command line as part of this process.
