Image hide_hypervisor_id property helps libvirt set an xml instance file
property, which will hide on guest host KVM hypervisor signature
("KVMKVMKVM\0\0\0").
According to the commit message in QEMU repository [1]:
"The latest Nvidia driver (337.88) specifically checks
for KVM as the hypervisor and reports Code 43 for the
driver in a Windows guest when found. Removing or
changing the KVM signature is sufficient for the driver
to load and work."
DocImpact: New feature ``img_hide_hypervisor_id`` image property should be
added in the glance-property-keys page of the cli-reference docs [2].
