Summary: Added 2 statistics in compaction job statistics, to identify if single deletes are not meeting a matching key (fallthrough) or single deletes are meeting a merge, delete or another single delete (i.e. not the expected case of put). Test Plan: Tested the statistics using write_stress and compaction_job_stats_test Reviewers: sdong Reviewed By: sdong Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D61749
