    Hyper-V: properly handle shared storage during migrations

    In case of migrations, we attempt to move the instance files without
    checking whether shared storage is used. Note that the block_migration
    flag is ignored.

    After a live migration is performed, we always try to delete the
    instance files. Also, if the migration fails, the destination node is
    not cleaned up, as the HyperVLiveMigrateData object is not used at the
    moment.

    This change addresses those issues.

    Partial-Bug: #1565895
