catborise 51dedb7b8f fix(instances): disk edits keep their XML; changes lock per VM
Disk edits:
- edit_disk built a new <disk> from the form and replaced the old one,
  losing what the form does not show (e.g. encryption and virtio
  driver options); a bus change detached and re-attached the disk.
  The disk of the persistent definition is now edited in place and the
  domain defined once; a bus change picks a free device name and drops
  the old address and virtio-only options. Pending persistent changes of
  a running VM are kept.
- Clone omits empty disk devices, refuses a disk without a supported
  source and destination, and checks the name before allocating storage.

Locks:
- Every VM change held its compute's exclusive lock, so one slow
  operation blocked all VMs on that compute. A VM change now holds its
  own VM lock plus a shared compute lock; reconciliation, migration and
  cloning hold the compute exclusively (two clones of different VMs
  must not pass the name check together).
- Quota-checked changes of one user (CPU, memory and disk resize,
  clone) run one at a time under a per-user lock, also across computes,
  so concurrent requests cannot all pass the check against the old
  allocation. It is the outermost lock; superusers, who have no quota,
  skip it.
- A busy lock answers 409 to the API and a message in the web UI. API
  power and destroy actions return the view's error instead of success.
