KUDU-2055 [part 5]: Coalesce hole punch for LBM
This patch extends the implementation of BlockDeletionTransaction to
actually coalesce hole punch in LBM, so that blocks in one container
that are contiguous are grouped together in a hole punch operation.
It also adds a new metric 'holes_punched' in log block manager to track
the number of hole punching operations. And another two metrics
'blocks_created' and 'blocks_deleted' in block manager to track blocks
that were created and deleted since service start respectively.
It updates unit test LogBlockManagerTest.MetricsTest, to verify that
coalescing hole punching works as expected by checking the value of
'holes_punched' metric.
