Revisit hyper client and api

[feiskyer]

The hyper client code should be separated from hyper CLI. And we should also add an optional gRPC api to improve performance.

• Separate client code and api code Separate client code and api code #263
• Prepare types for both current api and gRPC Prepare types for both current api and gRPC #279
  • proto definition
  • generate types.go
  • fix usage
  • verify in CI
• Clean up client/api/ code, move CLI related function to CLI itself
• Add ApiVersion to hyperd
• Make api more restful and return json object for all APIs
  • This will change API, consider related projects
