Upcoming patches will modify how we populate the capability cache in
tests to be more saner. This also means that the emulator binary and
architecture used in the test files using real capabilities must match
what the real capabilities have.

This commit extends libvirt XML configuration to support a custom encryption engine.
This means that <encryption format="luks" engine="qemu"> becomes valid.
The only engine for now is qemu. However, a new engine (librbd) will be added in an upcoming commit.
If no engine is specified, qemu will be used (assuming qemu driver is used).

Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable
- VNC - set to "none", unless passthrough of host env variable is set
- SPICE - always set to "spice"
- SDL - always passthrough host env
- No graphics - set to "none", unless passthrough of host env variable is set
The setting of the QEMU_AUDIO_DRV env variable is done in the code which
configures graphics.
If no <audio> element is present, we now auto-populate <audio> elements
to reflect this historical default config. This avoids need to set audio
env when processing graphics.

There is this class of PCI devices that act like disks: NVMe.
Therefore, they are both PCI devices and disks. While we already
have <hostdev/> (and can assign a NVMe device to a domain
successfully) we don't have disk representation. There are three
problems with PCI assignment in case of a NVMe device:
1) domains with <hostdev/> can't be migrated
2) NVMe device is assigned whole, there's no way to assign only a
namespace
3) Because hypervisors see <hostdev/> they don't put block layer
on top of it - users don't get all the fancy features like
snapshots
NVMe namespaces are way of splitting one continuous NVDIMM memory
into smaller ones, effectively creating smaller NVMe-s (which can
then be partitioned, LVMed, etc.)
Because of all of this the following XML was chosen to model a
NVMe device:
<disk type='nvme' device='disk'>
<driver name='qemu' type='raw'/>
<source type='pci' managed='yes' namespace='1'>
<address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
</source>
<target dev='vda' bus='virtio'/>
</disk>
