Add two additional stats (rewritten & out-of-order) related to writing chunks. chunks_rewritten tracks the number of chunks that the publisher has requested to be copied multiple times. chunks_committed_out_of_order tracks the number of times we saw a chunk_id that was behind the last one we saw. It does not track the reason why this occurred. Change-Id: Ib3279337235198faef7662e3480e53e50a83f650
