Feature: set QoS options to override durability (#250)

🎉 New feature

• Backport feat: set qos options to override durability #250

Summary

For future reference, this is necessary when bridging tf_static, because it expects a transient_local durability. We're planning to open a separate PR with a demo for how to do this, but here's an example:

      bridge = Node(
          package='ros_ign_bridge',
          executable='parameter_bridge',
          arguments=[
              # Bridge static poses from PosePublisher
              '/model/' + model_name + '/pose_static@tf2_msgs/msg/TFMessage[ignition.msgs.Pose_V',
          ],
          remappings=[
              # Remap to tf_static
              ('/model/' + model_name + '/pose_static', '/tf_static'),
          ],
         # Set correct durability for tf_static
          parameters=[{'qos_overrides./tf_static.publisher.durability' : 'transient_local'}]
      )

I can take up the demo in a separate PR :)
