Investigate feasibility of integrating with Sentry

[ccma14]

Description

In order to facilitate monitoring of a running tilenol integration, we should investigate the feasibility of integrating with Sentry. This should be optional, such that if tilenol is started with a Sentry DSN specified as an optional parameter then error reporting to Sentry should be enabled.

Good call @ccma14 . Fortunately it looks like Sentry maintains an official Go Client SDK and has plenty of readily-available documentation written about using it, which should serve as a good starting point for us.
