better JD health-checks

[Tofel]

This pull request enhances the health check capabilities for the Job Distributor (JD) component by introducing a new gRPC health check strategy and updating the CI pipeline to test JD startup using private container images. It also refactors the JD test to reside in the examples directory, improves port management in JD startup logic, and updates dependencies for gRPC support.

JD Health Check Improvements

• Added a new GRPCHealthStrategy in grpc_wait_strategy.go to perform robust gRPC health checks on the JD container during startup. This strategy uses the standard gRPC health protocol and supports configurable timeouts and polling intervals.
• Updated the JD startup logic in jd.go to expose both the main gRPC port and a separate health check port, and to use the new gRPC health check strategy as part of the container's wait conditions. Also added a check to prevent port conflicts between WSRPC and its health endpoint. [1] [2] [3] [4] [5]

CI Pipeline Enhancements

• Added a new GitHub Actions workflow (framework-golden-tests-private.yml) to run JD tests that require access to private container registries, including AWS ECR authentication and log upload.
• Updated comments in the public test workflow to clarify that tests requiring special authentication should be moved to the new private workflow.

Test Refactoring

• Moved the JD startup test from components/jd/jd_test.go to examples/myproject/jd_test.go, renamed the test for clarity, and added a random CSA encryption key for improved test isolation.

Dependency Updates

• Updated go.mod files to include or bump the google.golang.org/grpc dependency, ensuring compatibility with new health check functionality. [1] [2] [3]

Documentation

• Added a changeset entry to document the enhancement of JD health checks and the addition of a CI test for them.
