[bootstrap] Reduce the memory size consumed when bootstrap
When a tserver bootstraps, it loads all tablets metadata,
and finds out the maximum fs block id it has seen to notify
the block manager to avoid generating duplicate ids.
However, a tablet may contain a large number of blocks,
that means it consumes a large amount of memory when
tablets parellel loaded when tserver bootstrap.
This patch optimizes the tablet bootstrap to find the
maximum block id for a tablet without storing all the
block identifiers in the memory.
