This commit clarifies the origin of the REDIS_MASTER_SERVICE_HOST variable by linking to the documentation on the way kubernetes services create env variables in the services.md file.
As a replacement of a single SERVICE_HOST variable, offer a FOO_SERVICE_HOST
variable. This will help ease the transition to ip-per-service, where there
is no longer a single service host.
