Add per-service env vars for *_SERVICE_HOST

is no longer a single service host.

Add per-service env vars for *_SERVICE_HOST
Fix docker-links-style env vars for services

This includes 3 changes:

1) Use the Service.Protocol field, rather than hardcoding TCP.
2) Use Service.Port rather than ContainerPort - ContainerPort can be a string

3) Beef up tests for these env vars.
