## Open Tracking

Adds tracking pixels to messages and tracks whether they have been opened.
feat(new-plugins): add open tracking and link tracking plugins Summary: Adds two (very similar) plugins - Open Tracking and Link Tracking. Both can be enabled via a button in the composer. Open tracking inserts a tracking pixel right before send, and link tracking replaces all links with tracked redirects. Both plugins use the new Metadata service to store their open/click counts, and have backend servers to respectively serve the pixel image or handle the redirects. Requests also trigger a metadata update to increment the open/click counters.
