Chunk server: revise hello resume protocol. Maintain list of last in flight (at the time of the meta server disconnect) corrupt and available chunk lists, communicate this list to the meta server as part of the initial hello resume for meta server to remove the chunks present in this list from list from the inventory count and checksum, in order to allow unambiguous chunk inventory mismatch detection. The pending ops for chunks in this list are retried when connection to the meta server is re-established. Fix state transition in hello resume protocol.
Meta server implement reception and processing of the chunk exclude list in step 0 of partial chunk synchronization / hello resume.
