Project structure

├── integration_tests // integration test suite
├── migrations // migrations scrip use with go-migrate
├── repositories // entity definition

What need to be done

• maybe implement generic service handler (not depend on .proto type)
• better tracing, logging support from grpc-ecosysten
• clean tests code (I wirte them in rust with lot of copy/paste)
• HealthcheckService to check migration state
• a build env with Dockerfile with proto compiler, gogoslick
• a 'cache' Dockerfile to share betwee, app and integration_tests for save time pulling deps
• maybe better to have a Docker with auto-rebuild app
