The intent was primarily to aid in debugging libvirt by providing information
that is/was relevant to the libvirt guest configuration.
The instance metadata dict is not something that affects libvirt - IIRC it
is only relevant to the guest OS, so i don't think it is relevant to include
in the libvirt XML
