This change creates a new lms/cms endpoint which accepts unauthenticated requests to securely create zendesk tickets. This allows javascript code to create tickets without exposing ZENDESK_OAUTH_ACCESS_TOKEN EDUCATOR-1889
Zendesk API proxy endpoint
Introduced via EDUCATOR-1889
Purpose
This djangoapp contains no models, just a single view. The intended purpose is to provide a way for unauthenticated POST requests to create ZenDesk tickets. The reason we use this proxy instead of a direct POST is that it allows us to keep ZenDesk credentials private, and rotate them if needed. This proxy endpoint should be rate-limited to avoid abuse.
