Refactor traefik with package
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 Signed-off-by: Vincent Demeester <vincent@sbr.pm>
