Split a bit traefik into package. The idea behind this refactor is to
start move inter-dependencies away and do some DRY or SRP.
- Adds a `provider` package, with providers except `web.go`
- Adds a `types` package with common struct.
- Move `gen.go` to an `autogen` package

- Add a Makefile with common targets (binary, test, validate, ..)
- Use docker to build it (isolated)
And update circleci to work with the new Makefile..
