cli help text updates and flags cleanup (#1564)

* cli help text and flags cleanup

- verbose flag uses global setting throughout
- confirm flag added using shared visitor throughout
- path flag added using shared visitor throughout
- removes --version flag on root as redundant with subcommand
- splits main help's 'Main Commands' into 'Primary Commands' and 'Development
  Commands' groups
- Moves RunE definition into flag struct literals

* remove commented code
