Raphael S. Carvalho a0e0195a77 sstables: Avoid excessive reallocations when creating sharding metadata 
Let's reserve space for sharding metadata in advance, to avoid excessive
allocations in create_sharding_metadata().
With the default ignore_msb_bits=12, it was observed that the # of
reallocations is frequently 11-12. With ignore_msb_bits=16, the number
can easily go up to 50.
