    [BugFix] Change parameters for legacy bdm

    `_parse_block_device_mapping` method was design to support both
    bdm v1 and v2. The implementation is based on the fact that API side
    ignores unknown/incorrect parameters, so `_parse_block_device_mapping` compose
    equal parameter for bdm v1 and bdm v2. Since Nova V2.1 contains schema checks,
    such implementation stoped working.
    Despite the fact that novaclient.v2.servers contains separate logic for bdm v2,
    we can make `_parse_block_device_mapping` works only with legacy bdm and
    in future patches make it works for both bdm v1 and bdm v2.
