Function noDefaultsOptions

Strips the defaults from configured flags. For example, if flags contains:

  someFlag: Flags.boolean({
    description: 'some flag',
    default: false
  })
Copy

it becomes:

  someFlag: Flags.boolean({
    description: 'some flag'
  })
Copy

If we parse using this configuration, the only specified flags will be those the user actually passed on the command line.
