Description

Allow matching on a JSON body.

  1. Parse complete JSON object up to a buffer limit.
  2. Allow field selection matching.

This can potentially be accomplished via gRPC matching with implicit conversion to/from a Struct.

Contributor guide

Research direction
Examine the existing tap filter implementation in envoy to understand how matching works for other formats and where to add JSON body matching. Look for existing JSON parsing utilities in the codebase.
