## Description
Fix the following errors
### POST https://o296332.ingest.sentry.io/api/1546547/envelope/... 429
(Too Many Requests)
We have an integration with Sentry to instrument page loads and other
transactions. This is no longer used. All page load metrics are
collected using a new relic integration.
The sentry transactions api was throwing a 429 error when we exceed our
trial quota. Removing the integration should curb this error.
