New game lifecycle management method in stream provider

[isuru89]

When creating a game,

• A method in stream provider class must be called to initialize a game (e.g. initGame(options))
• When called this method, necessary streams must be created for the game
• For kafka, in this particular time, number of partitions should be specified

When closing a game,

• A method in stream provider must be called (e.g. closeGame(options))

If there is no game topic, the event-api should reject any events targeting that game.
