Need to finish

Deprecated features in v2 that could potentially be removed in v3

- configtxgen flag --outputAnchorPeersUpdate flag (instead, utilize channel config updates)
- fabric-tools image (instead, utilize client connection to network), note fabric-tools still used by fabric-samples as a convenience for jq commands
- Block dissemination via gossip (instead, configure all peers as org leaders to receive blocks from ordering service)
Identity Mixer deprecation/replacement
#3663 Fabric v3 epic misc items
- #3306 new channel config for CouchDB max_document_size, use during validation to prevent transactions too large to persist, along with application capability
