Camera synchronizer node should refresh camera config periodically (ros ticket #4151)

[ahendrix]

If you reload the controllers, images stop streaming. If you poke the camera synchronizer node through dynamic reconfigure it will start the cameras streaming again. Could we add periodic refreshing from the camera synchronizer node so the cameras start up again automatically?

[blaise] I have a fix ready for testing. What is the invocation you do to reload the controllers?

[ahendrix]

[sglaser] rosrun pr2_controller_manager pr2_controller_manager reload-libraries --restore

[ahendrix]

[blaise] What am I doing wrong? (This is running with the shared install. Is it too old?)

{{{
blaise@prm1: ~/pr2_camera_synchronizer $ rosrun pr2_controller_manager pr2_controller_manager reload-libraries --restore
Successfully reloaded libraries
blaise@prm1: ~/pr2_camera_synchronizer $ rosrun pr2_controller_manager pr2_controller_manager list
No controllers are loaded in mechanism control
blaise@prm1: ~/pr2_camera_synchronizer $
}}}

[ahendrix]

[sglaser] It looks like the shared install is too old. If you'd prefer not to upgrade, you can get the camera controllers back up like this:

{{{
rosrun pr2_controller_manager pr2_controller_manager spawn head_camera_trigger l_forearm_cam_trigger projector_controller projector_trigger prosilica_inhibit_projector_controller r_forearm_cam_trigger
}}}

[ahendrix]

[blaise] Should be fixed in trunk in #35203.
