Use NodeParametersInterface to track use_sim_time parameter for time source #2370
Description
Minor Enhancement
see
rclcpp/rclcpp/src/rclcpp/time_source.cpp
Line 280 in 411dbe8
it uses basically /parameter_events subscription to check the use_sim_time which belongs to the node.
but as mentioned TODO, this can be done more efficiently using NodeParametersInterface.
