Title: Add automatic throttling for LSM based on merge speed. Update merge_threads

The automatic throttling starts if there are too many chunks in an LSM tree
that have never been merged.

Increase the default number of LSM merge threads to 2 from 1. Since one
merge thread can now be pretty much dedicated to creating bloom filters.
