Summary: Added the column family name to the properties block. This property is omitted only if the property is unavailable, such as when RepairDB() writes SST files. In a next diff, I will change RepairDB to use this new property for deciding to which column family an existing SST file belongs. If this property is missing, it will add it to the "unknown" column family (same as its existing behavior). Test Plan: New unit test: $ ./db_table_properties_test --gtest_filter=DBTablePropertiesTest.GetColumnFamilyNameProperty Reviewers: IslamAbdelRahman, yhchiang, sdong Reviewed By: sdong Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D55605
