Migrate srv files from jsk_pcl_ros to jsk_recognition_msgs

[wkentaro]

Background

Some packages in jsk_visualization depends on jsk_pcl_ros because it uses the srv files.
But jsk_pcl_ros is a very large package and the dependency should be avoided ideally.
The solution is placing msg/srv files into jsk_recognition_msgs.

Plans

1. Merge this after jsk_recognition_msgs is released: http://repositories.ros.org/status_page/ros_indigo_default.html?q=jsk_recognition_msgs
2. Release this pacakge.
3. Remove jsk_pcl_ros/srv.
4. Release jsk_pcl_ros.
