Default Connect's Server.Address to ServiceName:Port when launcher.enabled

[dbkegley]

When Server.Address is not defined, can we set it to the default value <service.name>:<service.port> instead of defaulting to localhost:3939? This way at least within the Kubernetes cluster the Connect server will resolve. This would be particularly useful for the connectapi package which relies on Server.Address when setting the value for CONNECT_SERVER in the content runtime environment

Setting Server.Address is a requirement for all connect deployments.
