Hello, I've been looking at getting gazebo_ros_pkgs ready for indigo, and I
noticed that the gazebo_plugins package depends on driver_base, which is
listed as end-of-life on its wiki page. There are 12 packages listed as
depending on driver_base in hydro. Will / should it be released into indigo?

gazebo_plugins uses the SensorLevels msg from driver_base in three
dynamic_reconfigure files:
https://github.com/ros-simulation/gazebo_ros_pkgs/blob/hydro-devel/gazebo_plugins/cfg/GazeboRosCamera.cfg#L6
https://github.com/ros-simulation/gazebo_ros_pkgs/blob/hydro-devel/gazebo_plugins/cfg/GazeboRosOpenniKinect.cfg#L6
https://github.com/ros-simulation/gazebo_ros_pkgs/blob/hydro-devel/gazebo_plugins/cfg/Hokuyo.cfg#L41

SensorLevels msg for reference:
https://github.com/ros-drivers/driver_common/blob/indigo-devel/driver_base/msg/SensorLevels.msg

Should gazebo_plugins be doing this? We're open to suggestions, with the
goal of releasing soon for indigo.
