Unable to use TemplatedNaturalLanguageGenerator in NLG due to Sanic/uvicorn conflict

[moaazsidat]

Does it make more sense to put TemplatedNaturalLanguageGenerator as part of rasa_sdk instead of rasa.core.nlg, since we're using it like so:
https://github.com/RasaHQ/rasa/blob/master/examples/nlg_server/nlg_server.py#L57

The reason being that we're using something other than Sanic for our NLG server and are running into conflicting dependencies when trying to install rasa with the latest uvicorn installation due to the following Sanic/uvicorn incompatibility:
sanic-org/sanic#1629

Anyone with more knowledge of how rasa works internally comment on if this be relatively easily extracted to be part of rasa_sdk?
https://github.com/RasaHQ/rasa/tree/master/rasa/core/nlg

Or alternatively, should there be a rasa_nlg package?

Closing because not a question
