Mark Callaghan 409635cb2a Add --slow_usecs option to determine when long op message is printed (#9732) 
Summary:
This adds the --slow_usecs option with a default value of 1M. Operations that
take this much time have a message printed when --histogram=1, --stats_interval=0
and --stats_interval_seconds=0. The current code hardwired this to 20,000 usecs
and for some stress tests that reduced throughput by 20% or more.

This is for https://github.com/facebook/rocksdb/issues/9620

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9732

Test Plan:
./db_bench --benchmarks=fillrandom,readrandom --compression_type=lz4 --slow_usecs=100 --histogram=1
./db_bench --benchmarks=fillrandom,readrandom --compression_type=lz4 --slow_usecs=100000 --histogram=1
