[feature]: `cmdargs` with prompt

[azmizar]

Is your feature request related to a problem? Please describe.
Common need for a CLI (command prompt) type application is the need to provide command line arguments. This can be a mix of required and optional parameters. Also, ability to specify default value for the switches would be great.

Describe the solution you'd like

• Configs to specify all of the cmdargs
  • switches (-h or --help)
  • required or optional
  • default value
  • validator callback for the entered value
• (maybe) callback to show app usage if a specific flag is specified (ex: -h or --help)

Describe alternatives you've considered
Build this for each application and duplicating the code in each projects.
