KAFKA-8804: Secure internal Connect REST endpoints (#7310) 

Implemented KIP-507 to secure the internal Connect REST endpoints that are only for intra-cluster communication. A new V2 of the Connect subprotocol enables this feature, where the leader generates a new session key, shares it with the other workers via the configuration topic, and workers send and validate requests to these internal endpoints using the shared key.

Currently the internal `POST /connectors/<connector>/tasks` endpoint is the only one that is secured.

This change adds unit tests and makes some small alterations to system tests to target the new `sessioned` Connect subprotocol. A new integration test ensures that the endpoint is actually secured (i.e., requests with missing/invalid signatures are rejected with a 400 BAD RESPONSE status).
