refactor: seperate stream into it's own service and make it less of a pain to use

[90-008]

• seperate stream service
• stream service will have a streaming rpc
• this rpc will take a stream events request where the request type takes an enum containing all possible streaming services and the serialized request data for the chosen streaming service
• the rpc returns the same as request except the data is replaced with event data

TODO: better wording
