os/bluestore: make zone/span size of bitmap-allocator configurable #10040

  1. os/bluestore: make zone/span size of bitmap-allocator configurable 

    Perviously as zone_size_block and span_size are identical, so we could use
span_size only to simplify the calcuation.

Now that the zone_size_block and span_size are both configurable, so
it is necessary to treat them respectively.

  5. os/bluestore: add support for allocating 0-sized extent 

    For testing, we may choose randomized length of extent to allocate,
which means we could trim down the length to 0.
