Improvements to afrouterd.

- Added ability to run the afrouterd outside the cluster, using a URL & local kube-config instead of in-cluster config.
- Fixed a bug where the afrouterd would not wait for connectivity to the afrouter before starting its main loop.
  (grpc.Dial is async by default.)

This may or may not resolve VOL-1661.
