We should warn "PoseArray rviz plugin is deprecated in Kinetic, Melodic and Noetic"

[knorth55]

PoseArray rviz plugin is added in jsk_visualization for indigo and hyrdo devel because of upstream late response.
#349

However, the situation got changed, and we can use pose array default plugin in Kinetic, Melodic and Noetic...
Maybe we should warn that JSK version is deprecated, and switch to use rviz default plugin.

Currently, rviz dies when we load PoseArray in jsk_rviz_plugins subscribing messages whose elements are all zero.
You can check it by:

rosbag play poses_causing_rviz_death.bag --clock --loop
rviz -d poses_causing_rviz_death.rviz
