The HFiles generated by incremental backups cannot be properly read by tooling such as the ClientSideRequestScanner, because the generated HFiles do not include the MAX_SEQ_ID metadata. The scanner will ignore cell-level sequence IDs and instead sort the HFiles arbitrarily. This causes incorrect results when scanning overwrites to cells with the same timestamp. This PR adds a new option to the HFileOutputFormat2 that will calculate and set the required metadata. This only really effects the ClientSideRequestScanner, as the sequence ID will be recalculated when bulk-loaded anyways.
