db643e99 - createSourceEventStream: introduce named arguments and deprecate positional arguments (#3634)

createSourceEventStream: introduce named arguments and deprecate positional arguments (#3634) Deprecates the positional arguments to createSourceEventStream, to be removed in the next major version, in favor of named arguments. Motivation: 1. aligns createSourceEventStream with the other exported entrypoints graphql, execute, and subscribe 2. allows simplification of mapSourceToResponse suggested by @IvanGoncharov
