Venkatesh Radhakrishnan a98fbacfa0 Moving memtable related files from util to a new directory memtable
Summary:
We are cleaning up dependencies.
This diff takes a first step at moving memtable files to their own
directory called memtable. In future diffs, we will move other memtable
files from db to memtable.

Test Plan: make check
