ENOS management of Linux Kernel virtual machines (KVM) and Linux containers (LXC)

[jmacauley]

Feature will utilize ProxMox VE (https://www.proxmox.com/en/proxmox-ve) to dynamically create, delete, and generally manage Linux-based containers. This feature is required for NFV support, however, before this, it'll be used to create containers for user controllers, fake hosts, etc. Also required for site management.

This task should wait until deployment of proxmox on the testbed if complete.
