[LBM] Speed up server bootstrap by using multi-thread to compact containers
When a data directory has many low live block containers, a single thread to
compact these container metadata files is low efficiency, we can improve it by
multi-threads.
In some test cases, e.g. one or very few data directories, high latency disk
drivers, a large amount of low live block containers, and with a multi-core
CPU, this patch could reduce about 85% time in metadata files compact
procedure when bootstrap.
