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)
