a1465e661e conf: snapshot: Introduce 'manual' mode for snapshot of a disk
The idea of the manual mode is to allow a synchronized snapshot in cases
when the storage is outsourced to an unmanaged storage provider which
requires cooperation with snapshotting.

The mode will instruct the hypervisor to pause along when the other
components are snapshotted and the 'manual' disk can be snapshotted
along. This increases latency of the snapshot but allows them in
otherwise impossible situations.

In blockdev mode we support creating snapshots on all kinds of storage
that qemu allows us to format the image. Drop the part of the sentence
enumerating explicitly supported protocols.

025555236c docs: formatsnapshot: Move paragraphs describing 'disk' element together
There was another paragraph describing the attribute 'type' of the
'disk' element under the description of the subelements. Move it to the
top to get all relevant information in one place.
