Summary: As a preparation to support updating some options dynamically, I'd like to first introduce ImmutableOptions, which is a subset of Options that cannot be changed during the course of a DB lifetime without restart. ColumnFamily will keep both Options and ImmutableOptions. Any component below ColumnFamily should only take ImmutableOptions in their constructor. Other options should be taken from APIs, which will be allowed to adjust dynamically. I am yet to make changes to memtable and other related classes to take ImmutableOptions in their ctor. That can be done in a seprate diff as this one is already pretty big.
