System uuid is the uuid of the host scoped into its physical parent host. It is used in a context of nested hosts.

If the current host is a nested host, snapshot creation must be done through its physical parent host (because the "nested host" is actually a VM).

This PR add a new method in host class to get the system uuid (using dmidecode -s system-uuid).

With this uuid, we can then perform a snapshot of the VM nested host.

BLOCKED BY #455
