Install DC/OS on bare metal

Assume 5 physical nodes, or VMs, that will be used with ScaleIO storage

• All nodes have 2 CPU cores, 64GB of disk storage. Hardware or VM type needs to support CentOS 7.3.
• The Install bootstrap node needs 4GB of memory, Other node types might get by with 2GB, though the spec calls for more (32GB on Master and Boot node, 16GB on others), and 2GB is cutting it close on the Master node for sure.
• Assume a single NIC each, All on a common subnet - though other configurations may work
• Each node must have a hostname in DNS, with forward and reverse lookup working, DHCP is OK
