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.

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

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.
