Request to add a metadata to indicate whether the influx data point timestamp is from message timestamp or unit timestamp

[dan-du-car]

Summary

The telematic units add a UTC now() timestamp when it receives the message and publish it to NATS server. This can be inaccurate as there might be some delay between message generation and telematic unit publishing the message. This enhancement request is to update the units to use the message timestamp whenever possible.

Acceptance

• Code update to use message timestamp if the message has one
• Integration test
