Fix argument list in NeutronClientRemoteWrapper
Fix argument list in NeutronClientRemoteWrapper

When trying to get a cached NeutronHttpAdapter object, use:
  self.adapters.get((host, port), None)
instead of:
  self.adapters.get((host, port), None, *args, **kwargs)
since self.adapters is a dictionary.  Pass *args and **kwargs to the
NeutronHttpAdapter constructor.
