functionaltests: restart Integrations Server after ingestion (#15356)
* expose deployment id * add ecclient package * restart apm-server after ingest * refactor RunBlockingWait to restart APM Server This removes the previous implementation with document count checks and the logic that was trying to ensure ingestion was completed. The method now relies only on restarting the APM Server. (cherry picked from commit c230240) # Conflicts: # functionaltests/go.sum
