Adding support for reading/writing config from package.json

The following has been addressed in the PR:

• [ ] There is a related issue
• [x] All code has been formatted with prettier as per the readme code style guidelines
• [x] Unit or Functional tests are included in the PR

Description:

Adding the ability to read from .dojorc configuration from package.json. If the dojo key exists in your package.json...

{ 
  "dojo" : {
    "build-app": {
    }
  }
}

And .dojorc does not exist, the config will be read from package.json. When you try to write config, and it's stored in package.json, you get a confirmation.

You are using a "dojo" configuration in your package.json. Saving the current settings will update your package.json. Continue? [ (N)o / (Y)OLO ]:

Additionally, you can now pass a command name into the get() method in order to read configuration that belongs to another command. Note that this applies to read only. You still cannot write to another command's config.

All of this is to support future work on @dojo/cli-create-theme to read a list of themeable elements that will be stored in package.json.
