Kashyap Chamarthy 14071dfb11 libvirt: Deprecate `live_migration_tunnelled`
We are well above the required MIN_LIBVIRT_VERSION and MIN_QEMU_VERSION
(4.4.0 and 2.11.0, respectively) to get QEMU-native TLS[1] support by
default.

So we can now deprecate (and later remove) the support for "tunnelled
live migration", which has two inherent limitations: (a) it cannot
handle live migration of disks in a non-shared storage setup (a.k.a.
"block migration"); and (b) it has a huge performance overhead and
latency, because it burns more CPU and memory bandwidth due to increased
number of data copies, on both source and destination hosts.

Both the above limitations are addressed by the QEMU-native TLS support
`live_migration_with_native_tls`, which is the recommended approach for
securing all live migration streams (guest RAM, device state, and
disks).
