Golang test for developer (integrations)

Description

Implement simple integration grpc service.

Create HTTP client based on Client interface in service/client.go. Method GetGames should go to freetogame source (in query key platform you should pass only pc or mobile, implement validation for this) and receive list of games in json format, parse all available fields to Games struct.

Generate GRPC server based on proto/integration.proto and implement methods GetBalance and SendBet.

• GetBalance should validate following fields: token,player,platform,currency,game_id then make request to service method GetGames and find game according to game_id from grpc request if game is found then fill in field in GetBalanceResponse.game(field namings are the same) and make GetBalance request to service by Player.id (Here use any in-memory storage with prefabricated data by player_id)

• SendBet should validate all fields and check in-memory storage if player has sufficient balance otherwise thow error, subtract amount from balance and update in-memory storage and return updated balance.

Fork this repository so we can see it, update README.md with full documentation how to deploy and run this service. Optionally it will be nice to have unit tests and any usage of middlewares throughout this project.
