Do not acquire lock for total_bytes/total_rows for Buffer engine
...
When Buffer() is under preassure, acquiring per-layer lock may take
significant time. And so the following query may take significant amount of time:
SELECT total_bytes, total_rows FROM system.tables WHERE engine='Buffer'

Add ability to flush buffer only in background for StorageBuffer

Add 3 new engine arguments:
- flush_time
- flush_rows
- flush_bytes
That will be checked only for background flush, this maybe useful if
INSERT latency is "crucial".

Add metric to track how much time is spend during waiting for Buffer layer lock
...
It uses very fast CLOCK_MONOTONIC_COARSE, so this should not be a
problem.
Also note that there is no sense in using microseconds/nanoseconds since
accuracy of CLOCK_MONOTONIC_COARSE usually milliseconds.
