Add network simulator support for force10 OS 10
Adds necessary logic to support spinning up a local network simulator for Dell Force10 OS10 switches which is a Linux based operating system image as opposed to the former force10 OS 9 switches. This change takes a *very* similar approach to OS9 support, but there are several differences between OS9 and OS10, mainly in configuration formatting, commands, access control, and even the overall virtual machine installation process which leverages ONIE and multiple "disk" artifacts.
