Implement basic memory management for OT server

[gohabereg]

Until we implement some database for OT server we need to manage memory usage

• When a new client connects to the server, it passes it's document state
• If it's the first client for the document, OT server initalizes the document with passed state
• If it's no the first client, OT sends the document current state to the client

Also added Dockerfile and compose config for OT server
