[Bug]: messageId not listed as valid parameter to .track()

[kentlarsson]

Where on segment.com/docs did you see this issue?

https://segment.com/docs/connections/sources/catalog/libraries/server/node/#track

What browsers are you seeing the problem on?

Chrome

Please describe the issue.

The documentation does not mention that you can send messageId (from JS, I guess it is named message_id in their other clients), even though that is what you have to send for handling duplicate data.

Looking at the source code for the JS client it explicitly uses the messageId passed in if there is one, or generates one if there is none.

@stayseesong Can you take a look at this one when you have a moment?
