Summary: I created a separate class ColumnFamilySet to keep track of column families. Before we did this in VersionSet and I believe this approach is cleaner. Let me know if you have any comments. I will commit tomorrow. Test Plan: make check Reviewers: dhruba, haobo, kailiu, sdong CC: leveldb Differential Revision: https://reviews.facebook.net/D15357
