Can we put the following codes in some Util classes?

[XinyueZ]

Let's consolidate these frequently copy-pasted codes into an ADK-util class to avoid repetition.

async def run_agent(query, agent):
  """Sends a query to the agent and prints the final response."""

  print(f"\n>>> User Query: {query}")

  # Create a Runner
  runner = Runner(
      agent=agent,
      app_name=APP_NAME,
      session_service=session_service
  )

  # Prepare the user's message in ADK format
  content = types.Content(role='user', parts=[types.Part(text=query)])

  final_response_text = None
  # We iterate through events from run_async to find the final answer.
  async for event in runner.run_async(user_id=USER_ID, session_id=SESSION_ID, new_message=content):
      if event.is_final_response():
          if event.content and event.content.parts:
             final_response_text = event.content.parts[0].text
          break
  print(f"<<< Agent Response: {final_response_text}")
