required steps to run container properly

[tobi-hasura]

it would be really helpful to make it explicit that the following lines are necessary to run the container properly

connector = FunctionConnector() and

if __name__ == "__main__": start(connector)

ndc-python-lambda/connector-definition/template/functions.py

Line 19 in 4cb6f2a

connector = FunctionConnector()

thank you!
