Description of contribution in a few bullet points

When using a PointCloud2 source, nav2_costmap_2d's ObstacleLayer plugin won't clear obstacles detected on the ground when they move away, as the <source>.min_obstacle_height parameter either will filter out the ground for the raytracing (if set to > 0.0) or detect it as an obstacle (if set to 0.0).
This problem is similar to #662.

This PR adds a new global min_obstacle_height parameter, allowing the per-source one to be extended to include the range to be taken into account for the retracing, while still filtering obstacles down to that new limit.

This allows considering full range observations, specified by the
  <data source>.min_obstacle_height
and
  <data source>.max_obstacle_height
especially used for the raytracing, but to still be able to specify a
minimum obstacle height to report obstacles onto the costmap.

This is in particular required in the case a PointCloud2 source points
slightly towards the ground, sometimes detecting obstacles, that should be
cleared once the ground reappears behind the obstacle when it has moved
away: we don't want to detect the ground as an obstacle, but still want it
to be used in the raytracing to clear the previously detected obstacle.
