Description
Two extended metadata fields, adjusted_time and conflict_resolution_mode, have been added to memcached and dcp to support last-write-wins(lww) conflict resolution by XDCR. gomemcached (and possibly go-couchbase) needs to be changed to accommodate the extended metadata.
The design doc for lww is at https://docs.google.com/document/d/1xBjx0SDeEnWToEv1RGLHypQAkN4HWirVqQ-JtaBtlrI/edit?usp=sharing
The memcached and dcp protocol changes are in: https://issues.couchbase.com/browse/MB-12692
