[Libosinfo] [osinfo-db PATCH v3 01/12] schema: Add support to Guest Features

[Fabiano Fidêncio]

Let's add support to have the list of features supported by OS. It's
quite important to note here that the feature being supported doesn't
mean it'll automatically work out of the box as it may depend on also
having whether QEMU or kernel have the right configuration.

The features supported by now are:
- cpu-hotplug
- hyperv
- hyperv-evmcs
- hyperv-frequencies
- hyperv-ipi
- hyperv-reenlightenment
- hyperv-relaxed
- hyperv-reset
- hyperv-runtime
- hyperv-spinlocks
- hyperv-synic
- hyperv-tlbflush
- hyperv-vapic
- hyperv-vendor-id
- hyperv-vpindex
