Install a Nomad cluster with Consul on cloud servers

[gselva]

Problem

This line is a bit confusing retry_join should contain at least one of your servers internal IP adresses as it is not clear which "servers" is meant.

Suggested Fix

The line would be clearer like this:
retry_join should contain at least one of your other servers internal IP adresses (do not use the internal IP of the server where you are updating this setting)
