Use system time for CDASim

[adev4a]

PR Details

Adds environment variable to check if ros2 nats bridge is being run in simulation environment. In case it is, the ros messages are stamped to system time at time of processing in the bridge.

This is required since the the ros message headers are stamped to simulation time which may not be reasonable values to plot on the dashboard.
