Forbid creating VM with name 'none' or 'default'
Those were special names in Qubes 3.x, don't allow such VMs to avoid
(potentially fatal) confusion.

vm/adminvm: add default_dispvm property to AdminVM
This is useful to select default DispVM template for VMs started
directly by the user. This makes sense as long as AdminVM == GUIVM.

vm/dispvm: add auto_cleanup property, unify creating new DispVM
Add auto_cleanup property, which remove DispVM after its shutdown
- this is to unify DispVM handling - less places needing special
handling after DispVM shutdown.

New DispVM inherit all settings from respective AppVM. Move this from
classmethod `DispVM.from_appvm()`, to DispVM constructor. This unify
creating new DispVM with any other VM class.
Notable exception are attached devices - because only one running VM can
have a device attached, this would prevent second DispVM started from
the same AppVM. If one need DispVM with some device attached, one can
create DispVM with auto_cleanup=False. Such DispVM will still not have
persistent storage (as any other DispVM).

Tests included.

storage: move volume_config['source'] filling to one place
Don't set 'source' volume in various places (each VM class constructor
etc), do it as part of volume initialization. And when it needs to be
re-calculated, call storage.init_volume again.

This code was duplicated, and as usual in such a case, those copies
were different - one have set 'size', the other one not.

app: do not create 'default' storage pool
Since we have app.default_pool* properties, create appropriately named
pool and let those properties choose the right pool. This also means we
don't need to specify pool name in default volume config anymore

vm/dispvm: fix DispVM storage definition
Specify empty 'source' field, so it gets filled with appropriate
template's images. Then also fix recursive 'source' handling - DispVM
root volume should point at TemplateVM's root volume as a source, not a
AppVM's one - which is also only a snapshot.

vm: drop old is_outdated/commit_changes
This code is unused now. Theoretically this is_outdated implementation
should be moved to FileVolume, but since we don't have VM reference
there, it isn't possible to read appropriate xenstore entry. As we're
phasing out file pool, simply ignore it for now.

vm/qubesvm: have VM lifecycle related events async

devices: make attach/detach related events async
This will allow starting processes and calling RPC services in those
events. This if required for usb devices, which are attached using RPC
services.
Intentionally keep device listing events synchronous only - to
discourage putting long-running actions there.

This change also require some not-async attach method version for
loading devices from qubes.xml - have `load_persistent` for this.

vm/adminvm: setup libvirt_domain property
Since libvirt do provide object for dom0 too, return it here.
It's much easier than special-casing AdminVM everywhere. And in fact
sometimes it is actually useful (for example attaching devices from/to

vm/qubesvm: forbid changing VM name
We've decided to make VM name immutable. This is especially important
for Admin API, where some parts (especially policy) are sticked to the
VM name.

Now, to rename the VM, one need to clone it under new name (thanks to
LVM, this is very quick action), then remove the old one.
