Alessandro Boch 1fae5573d2 Refactor NetworkController interface
- To reflect work flow. NewDriver() => ConfigureDriver()
  and no NetworkDriver returned.
  libnetwork clients would refer to a driver/network type, then
  internally controller will retrieve the correspondent driver
  instance, but this is not a concern of the clients.
- Remove NetworkDriver interface
- Removed stale blank dependency on bridge in libnetwork_test.go
