Cloud update for firmware

[kodjima33]

Firmware on Friend's wearable should be able to be updated via cloud

reference

Ideal scenario:
All friend's firmware should check our github folder and auto-update once it has internet connection>

"ok" scenario: Friend's firmware should be able to update via the mobile app "appwithwearable"

User-story: As a user, I want to be able to open Friend's app, connect to my wearable, then click "update". It should update the firmware from github

So it looks like with the bootloader in place, we should be able to utilize nordic's swift and java libraries to do the updating for us from the app. Adafruit's bluefruit le connect app is an example (see this dir).
