Error event logging and alerts

[0xean]

Background

Currently our primary app does log some error events to mixpanel but from my understanding we haven't historically used them much for taking action such as knowing a bad release went out if error rate spikes. While this would be a larger task to start getting better error reporting out of the main application, memoless presents an app with 1 critical flow that we might be able to experiment with some better error reporting and alerting so we aren't so reliant on users reporting bugs as the primary trigger to roll back a release.

Mixpanel also does offer custom alerts that could be monitored by operations.

Acceptance Criteria

• add mix panel event triggers for event triggers or anticipated bad states to the new og app
• determine how best to get decent information out of these events that help with debug-ability / traceability
• create a mixpanel dashboard to track these errors
• create an alert with the assistance of operations that can be monitored by them

The primary goal of this would be to move towards less reliance on users and being more proactive when a bad release goes out the door hopefully reducing the time it takes us to get a fix out (mttr type metric, which we don't actually track, yet)
