Move msg/srv from rosapi and rosbridge_library into separate packages…

…; enable Rolling in CI (#665)

**Public API Changes**
The msg and srv interfaces under `rosapi` are moving to a new package `rosapi_msgs`. The ones from `rosbridge_library` were used only for testing and are moving to a new package `rosbridge_test_msgs`.


**Description**
Fixes #581. Closes #602.
Due to a [change](ros2/rosidl_python#131) in rosidl_python, the generated python packages containing msg classes were conflicting with the python package these libraries export (ros2/rosidl_python#141). The solution recommended in that thread was to split these definitions into separate packages.
