Now that we have the controller, we would like to take min_threshold as
a hint. If there is nothing to compact, we can ignore that and start
compacting less than min_threshold SSTables so that the backlog keeps
reducing.
But there are cases in which we don't want min_threshold to be a hint
and we want to enforce it strictly. For instance, if write amplification
is more of a concern than space amplification.
This patch adds a YAML option that allows the user to tell us that. We will
default to false, meaning min_threshold is not strictly enforced.
