Keys in the dictionary are as follows:
uuid: system-uuid from dmi or /sys/hypervisor
uuid_source: 'hypervisor' (/sys/hypervisor/uuid) or 'dmi'
serial: dmi 'system-serial-number' (/sys/.../product_serial)
asset_tag: 'dmidecode -s chassis-asset-tag'
vendor: dmi 'system-manufacturer' (/sys/.../sys_vendor)
On Ec2 instances experimentation is that product_serial is upper case,
and product_uuid is lower case. This returns lower case values for both.
