Generise for all uses

[harrytwright]

As I would like to use this as my base for all the CLI based systems, be is a service, or a CLI itself, this needs to be generic but also customisable

Future may be depreciated for a fork of npmcli/config but for now, it needs work.

TODO:

• [ ] Better options
  • [ ] Set the envMap there, or if a env-prefix is passed it will work like REACT_APP_X or npm_config_x
• [ ] Async loading and Sync loading
  • [ ] Load configuration files if needs be.
  • [ ] Create overloads for index soConfig.constructor is never passed back ??

Coming back to this, nearly a year late, since it worked so wasn’t any need to fix this just yet.

But coming:

Ideas

• Single object constructor, using an object to pass all the data down new Config({ ... })
• Not going to add the loading of configuration files, that is overkill, as it’s primary usage is for cli options and mixing it with enviromental variables
• A better options prefix, so we can use the above: ‘Set the envMap there, or if a env-prefix is passed it will work like REACT_APP_X or npm_config_x’
