Installing Nomad on Three Servers

In this Lab, we will be configuring three provided nomad servers to be in a cluster. These servers are Centos 7 servers. One server will be configured as the server agent. The other 2 nodes will be configured as clients. At the end, we will have a small cluster that will be ready to accept and run jobs. You will need to make changes to the configuration to ensure that a data center of `dc1` is being used.
