Support High Precision Event Timer (HPET) on x86 guests

Registered by Jack Ding

HPET is currently turned off for x86 guests in the libvirt driver. This blueprint enables HPET to be set through image property “hw_time_hpet". By default it remains turned off.

HPET can be turned on by CLI:
$glance image-update --property hw_time_hpet=true <image-id>
