Don't default to master host-uuid if sr-create shared=false

sr-create had been defaulting the host-uuid to master if it wasn't
specified. This would cause problems when creating a local SR without
specifying the host-uuid. We now raise a CLI exception if we create
non-shared SR without specifying the host-uuid.

CA-129192: restore metadata for all SR

CA-129192/SCTX-1728: revise restore-sr-metadata.py so that it could restore
metadata for all SR with command line:
   ./restore-sr-metadata.py -f <input file> -u all
or just omit the sr-uuid:
   ./restore-sr-metadata.py -f <input file>

xe-restore-metadata is modified accordingly.

VDI.export: allow the user to specify a format; currently either 'raw' or 'vhd'

The HTTP handler accepts an additional argument:

  GET /export_raw_vdi?vdi=<vdi>&format=<raw|vhd>...

The content-disposition HTTP header is used to suggest a useful filename, and
the content-type HTTP header is set to either application/octet-stream or
application/vhd.

The CLI accepts an optional argument:

  xe vdi-export uuid=<uuid> filename=<filename> [format=(raw|vhd)]

.vhd format export will require a newer vhd-tool (>= 0.6.5)

Revert "CA-118466: Prevent snapshot revert from deleting VM VDIs that were attached"
Fixes CA-121278

This reverts commit 6989a08e8244a8c10318940ea65109e2169ff243.

The logic to skip disks attached after the snapshot isn't quite right,
and is causing problems in our test infrastructure by filling the storage
with disks which really should have been removed.
