[FEATURE/QUESTION] Forward value from jwt token to service in header

[4n70w4]

Hi! Thanks for plugin!

I have a need to pass a value from the jwt-token, for example, sub and forward it to the target service, for example, as a header.

I didn't understand if there was such a possibility and how to implement it.

For example: set rate limit by value from jwt-token.
