Using Docker provider, you can specify `traefik.frontend.rule` and
`traefik.frontend.value` labels. If they are not both provided, there is
a default behavior. On the current master, if they are not defined, the
container is filtered (and thus the default behavior is broken).
Fixes that.

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
