Add direct Firebase integration to the android app
Since the Firebase SDK sends events automatically when installed, it should be configurable on build time via the config file.
Notes: We found two ways to not fire the automatic events via config
1. if conditional in the gradle file to no apply the google-services plugin. This plugin takes the google-services.json file and then added the information as android resources which the Firebase SDK will look for.
2. There should be a way to tell Firebase to not fire any events after loading. More details found in https://openedx.atlassian.net/browse/MA-2980
Seems like either way, we will have to compile the dependency (from what I've looked at so far)
