WIP: Make BT nodes have configurable wait times. (ros-navigation#3960)

* Make BT nodes have configurable wait times. Previous solution provided hardcoded 1s value. Right now the value can be configured for BT Action, Cancel and Service nodes. [ros-navigation#3920] Signed-off-by: Adam Galecki <[email protected]> * Make BT nodes have configurable wait times. Previous solution provided hardcoded 1s value. Right now the value can be configured for BT Action, Cancel and Service nodes. [ros-navigation#3920] Signed-off-by: Adam Galecki <[email protected]> * Fix typos, linting errors and value type from float to int * Fix extra underscores * Fix extra underscore * Update unit tests with blackboard parameter Signed-off-by: Adam Galecki <[email protected]> * Fix formatting errors Signed-off-by: Adam Galecki <[email protected]> * Update system tests to match new parameter Signed-off-by: Adam Galecki <[email protected]> --------- Signed-off-by: Adam Galecki <[email protected]>
