Tagged Commands

[coreybutler]

As I've used this library to build applications, I've recognized a need for experimental commands, beta commands, and even hidden commands (hidden from help).

It would be nice to have a "tag" or some other identifier to identify which commands are experimental, which should be hidden, etc.

One possible implementation is:

new Command({
  name: 'cmd',
  tags: ['beta'],
  async handler () {...}
})

Special tags may have special documentation/help features:

• hidden: available, but does not show up
• ignore: completely ignore the command (won't run)
• experimental: prefixes description with EXPERIMENTAL.
• deprecated: prefixes description with DEPRECATED.

Tags should be exposed to command handlers and directly through the shell, making it possible for developers to create custom functionality for tagged commands.
