Fixing build error introduced by #1356

* Handle action server deactivation while the action is still running.
* Handle race condition between completing an action and receiving a preemption.
* Terminate all goals if cancel was requested on any goal handle.
* Terminate only the current goal if the module fails to execute the action.

Added parallel recovery behaviors

* changing behavior tree to use snake_case actions

* correct action servers not related to recovery

* resolve recovery server plugin names with action server names

* changing references from local planner to controller outside of DWB

* change minimum in DWB planner to be controllers

* Update nav2_core/include/nav2_core/controller.hpp

deleting robot package

Extended the SimpleActionServer interface and improved a few other things:
* Added additional checks to make sure we only keep the latest preempt request in the queue.
* Action server users no longer interact directly with the goal handles. 
* Provided additional functions for aborting, canceling, etc.
* Updated bt_navigator, motion_primitives, dwb_controller, navfn_planner to use the new interface.

Refactored the DWB controller main loop.
* Added checks for handling pending preemptions after the controller has succeeded or failed.

* Precise control of the contained node to improve shutdown reliability

* Add a couple TODO comments about further reducing code, eliminating duplication
