refactor: Add Api Server service modules for Dependency Injection

* Part of a broader paradigm shift towards Dependency Injection and
  Factory Pattern.
* Adds "api-server" service to docker compose
* Replaces MarketDataClient w/ IMarketDataClient in a few streams
* Replaces ViewStreamDatabase w/ IWorkScheduler in a few streams
