KUDU-2055: Coalesce hole punching when deleting groups of blocks
Similar to 'BlockCreationTransaction', this patch adds a new layer
of abstraction at Block Manager to coalesce blocks deletions in a
logical operation, e.g. compaction.
By coalescing blocks deletions, the number of hole punching in LBM
will be reduced from one per block to one per log block container.
This should overall optimize the performance of operation that
involves batch deletions, such as compaction and hole repunching.
