Note: Samson is a public repo, do not include Zendesk-internal information, urls, etc.

Description

Add a plugin to enable use of Sentry with the use of the SENTRY_DSN environmental variable (along with the existing PLUGINS environmental variable)

Risks

• Low: All executable code is behind a Sentry-specific Env var. The only effect of enabling it is logging.
