flipper-server refactor

Summary:
This changes moves most of the functionality found in flipper-server to flipper-server-core.

flipper-server will mostly be a package that wraps around flipper-server-core. Staying in flipper-server:
- Command line args
- Orchestration to start the necessary servers
