Bullet Collision Detection (moveit#1504)

* Added discrete BVH Bullet manager
* Added continuous collision detection
* Cleanup of tesseract code
   * removed simple collision managers
   * changed enum to enum classes
   * fixed typos
   * removing debugging statements
   * removing tesseract allowed collision matrix
   * removed tesseract macros
   * replaced typedefs of stl containers
   * removed tesseract attached object code
   * ACM members of collision robot and world removed and ACM check into callback out of class
   * remove ContactTestType and replace through MoveIt CollisionRequest
   * BodyType int changed to enum
   * removed tesseract_msgs dependency and unnecessary tesseract code
   * changed dependency from bullet3_ros to debian Bullet package

* Adding bullet and tesseract simple collision manager to the template:
   * added benchmark case for checking collision speed
   * tests for bullet collision checking

* Adding missing features:
  * attached objects
  * contact reporting max number of contacts fixed
  * Bullet plugin xml name fixed
  * padding and scaling for robot added
  * updated tests

 To use Bullet as a collision checker you can:
 a) create a new planning scene and manually switch to Bullet using the planning_scene.setActiveCollisionDetector()
 b) manually switch to Bullet using the `CollisionPluginLoader`
-c) manually instantiate a `CollisionRobotBt` and `CollisionWorldBt`
+c) manually instantiate a `CollisionRobotBullet` and `CollisionWorldBullet`
 d) use rosparam to set the collision checker (preferred but not tested yet) when starting a new `move_group`
