Support High Precision Event Timer (HPET) on x86 guests

Registered by Jack Ding on 2018-09-27

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>
