qemuserver: migration: test_volid: change attr name and ref handling

Since we don't scan all storages for matching disk images anymore for a
migration we don't have any images found via storage alone. They will be
referenced in the config somewhere.

Therefore, there is no need for the 'storage' ref.
The 'referenced_in_config' is not really needed and can apply to both,
attached and unused disk images.

Therefore the QemuServer::foreach_volid() will change the
'referenced_in_config' attribute to an 'is_attached' one that only
applies to disk images that are in the _main_ config part and are not
unused.

In QemuMigrate::scan_local_volumes() we can then quite easily map the
refs to each state, attached, unused, referenced_in_{pending,snapshot}.

The refs are mostly used for informational use to print out in the logs
why a disk image is part of the migration. Except for the 'attached' case.

In the future the extra step of the refs in QemuMigrate could probably
be streamlined even more.
