(hironx_ros_bridge) Trying to remove dependency on pr2 components.

DO NOT MERGE YET. 

Trying to replace `pr2_controllers_msgs` with `control_msgs`, which is available even on Groovy.
However this PReq didin't work out of the box -- In order to remove the dependency on `pr2_controllers_msgs`, we first need to do so in the upstream, i.e. `hrpsys_ros_bridge`.

```
$ rtmlaunch hironx_ros_bridge hironx_ros_bridge_simulation.launch
