As a ONAP developer, I would like to support JSON based schema in apex-pdp to provide capabilities of defining the structure of input & output events for a policy implementation.

This will also provide users with an option against the only supported AVRO schema, which has bunch of limitations and workarounds.

Approach

• A new plugin (maven sub-module) will be added under plugins-context-schema sub-module in apex-pdp.
• examples-grpc sub-module will be updated to use the new plugin for JSON schema.
• Relevant CSIT test cases will be updated/added.
• Relevant documents will be updated/added.
