Add virtualization features to sitesonar

This script inspects the output from lscpu and checks if some virtualization related fields are set.

Output examples:

• virtualization is enabled, but it does not run in a virtual machine:{ "Virtualization:": " AMD-V", "Hypervisor vendor:": "N/A", "Virtualization type:": "N/A"}
• it runs inside a KVM virtual machine: { "Virtualization:": "N/A", "Hypervisor vendor:": " KVM", "Virtualization type:": " full"}
