Description

This PR will change the way gen3 and above configure wifi:
Since ControlRequest doesn't allow to pre-load wifi credentials, we have to change the wifi configuration to use serial

How to Test

1. Pull down the branch: git pull && git checkout feature/sc-126610/make-particle-cli-uses-serial-to-configure
2. Install dependencies: npm i
3. Attempt to manually configure a p2 / argon device:
   • npm start -- usb listen
   • npm start -- serial wifi
4. Attempt to configure a p2 / argon device with a file (make sure that network can't be reached out):
   • npm start -- usb listen
   • npm start -- serial wifi --file /path/to/my/file.json
   • Go to wifi-tool and verify your configured networks

Tested to work with a Wi-Fi network that exists and one that doesn't exist on an Argon and Photon 2. I tested manual input and JSON file input.
