Convert all wall timers and wall rates to ROS clock respecting rates …

…and timers (ros-navigation#4000)

* Convert all wall timers and wall rates to ROS clock respecting rates and timers

* linty mclint face

* WPF wait plugin respect time

* move duration metrics to use local clocks

* bumping version for cache to break it

* complete timing refactor

* remove old variable
