Schema Registry Proposal

[JeffNeff]

Proposal: Include a common package for the brokers that allows them access to user provided schema definitions .

The user can provide the broker with a path to a folder containing CRD's (local or public/internet I.E one could point to https://github.com/triggermesh/triggermesh/tree/48061197f7bacc33477a6576752eeac45978ffee/config) and the package will illiterate over all of the files to look for a registry.knative.dev/eventTypes parameter .

From here the package can make the following information available to the Broker: The event type, schema definition, and a small description.

With the broker now equipped with this information we can begin to leverage it by:

• Autogenerate swagger endpoint
• Event type validation.
• Payload validation.
• Auto Transformation / AI transformation
