Live boot environment for qcacher

[Stealthii]

Create a variety of live boot environments that can run qcacher headless with minimal/no configuration, to better facilitate home LANs and quick setups.

Consider the following:

• LiveCD (only needs to download images)
• Live iPXE boot (downloads (CoreOS and images)[https://coreos.com/blog/boot-on-bare-metal-with-pxe.html])
• VM image (CoreOS tweaked for Xen, KVM, Hyper-V, VMware, Virtualbox, etc.)
