deploy-workers docs missing ports for api-server

[pgburt]

Problem

Missing a port on --api-servers recommendation.

https://coreos.com/kubernetes/docs/latest/deploy-workers.html#create-the-kubelet-unit

Proposal

Confirm we need a port and add to docs, or make it clearer where the port is declared.

Source

From the kubernetes Slack:

the line that says —api-servers=${MASTER_HOST}, it should probably say —api-servers=http://${MASTER_HOST}:8080, as throughout the docs ${MASTER_HOST} is always replaced with just the master’s IP address.

Since tls is explained, would this instead be --api-servers=http://${MASTER_HOST}?

Actually, it is fixed in master due to this commit: https://github.com/coreos/coreos-kubernetes/commit/80b323b41f473cca52f9d22a2ccf40403e64d5bd
