vmx: Add support for VDS interface

Since we cannot properly plug a new VM into the distributed switch, we can at

even for VMs with such interfaces.

qemu: command: Always assume support for QEMU_CAPS_SCSI_DISK_DEVICE_ID

The 'device_id' property of 'scsi_disk' was added in qemu-4.0 and it's
unconditionally present, thus we can now always assume its presence.

Update some fake-caps test which didn't yet assert the capability.

qemu: Refactor access to 'qomName' field of the qemu disk private data

The code which fills 'qomName' does so only when the blockdev capability
is enabled so we don't have to check it separately as it can be only
non-NULL when blockdev is used.

Until we finish removing the capabilities we need to force them in the
tests so that it's obvious that the code changes have no impact.

qemu: capabilities: Unconditionally set QEMU_CAPS_BLOCKDEV/QEMU_CAPS_BLOCKDEV_HOSTDEV_SCSI

The cleanup of the code to always assume support for QEMU_CAPS_BLOCKDEV
will not be simple, so for now we hardcode the support and the code will
be cleaned up gradually.

We also disallow users to clear the flags via the namespace property or
qemu.conf configuration.

The change to the PPC64 test data originates from the fact that the
capability dump is not from the release version but is lacking one of
the necessary flags to enable -blockdev.

This will remove all uses of QEMU_CAPS_QCOW2_LUKS from the test suite.
