    Description

      See MB-56621 and MB-49779 for more details.

      The summary is - KV accepts two options for `enable_out_of_order_snapshots` DCP Control message - ["true", "true_with_seqno_advanced"].

      Currently the go SDK does not support the latter option above^. See:

      https://github.com/couchbase/gocbcore/blob/v9.1.8/dcpagent.go#L174 

      The `true_with_seqno_advanced` control message is pivotal for consumers (FTS in this case) to right the expectation of what seqnos KV will send especially when purged tombstones (from expired/deleted items) are involved.

      I'm requesting support for this as soon as possible in the v9 and v10 branches for gocbcore. This is blocking our 7.2.0 server release.
