cron job for sending push notifications. deadline 4/4

[mjrb]

Using the python firebase admin sdk, we can send notifications to specific people who have subscribed to a certain topic. for example we will have a topic for announcements, and a topic for each mini event on the calendar.
essentially we need a lambda that will check the calendar and slack every n minutes (n is defined in config perhaps).
if the lambda notices a calendar event is soon, or that there is a new announcement it will send a notification to the correct topic.

exact topic names TBD. just use announcements and events for now
More research needed to determine how to do a cron job (running something every n minutes) with lambda or SLS framework.

ask me for Firebase credentials if you are working on this

here is a link to what seems like the appropriate documentation in the python firebase admin sdk
here is a rough example of how to send a notification to a topic, but it doens't show how to setup the client :/
