Firebase cloud functions

Install firebase tools:

npm i -g firebase-tools

What the heck is a cloud function?

What the saveKey function does:

• accepts a POSTed pubic RSA key (as JSON)
• validates the JSON against the document DB schema
• inserts the document into our Firestore 'devicePublicKeys' collection

What the saveImage function does:

• accpets a form POSTed png image (done using curl)
• strips the form header
• saves the image to the uploads storage bucket.

For the IoT registration POST from the device, See the brain script:

scripts/iot/one_time_key_creation_and_iot_device_registration.sh

For the image file POST from the device, See the brain script:

scripts/iot/send_image_test.sh
