[http][example] Finish icehub without database

[at15]

Now the example can accept oAuth, but is just barely usable

Server

• [ ] http access logging
  • might need to hjack http handler or writer to know the size of payload
  • [ ] how to know request size and response header (especially code)
  • use standard apache/nginx access log format / mix w/ gommon/log
• [ ] https support
  • [ ] already have self signed cert using openssl
  • [ ] let's encrypt, many go project has it (auto TLS ...) #15
  • needed to deploy the test service that integrate with GitHub
• [ ] clean up the app.go , still a bit annoyed about its structure
• [ ] tracing support
• [ ] (optional) session

Server & Client

• [ ] share service interface
  • [ ] use gRPC to generate?
  • or maybe https://github.com/twitchtv/twirp

Client

• [ ] http client

Data

• [ ] just store things in memory for now
