v0.12.0

[romange]

Dragonfly v0.12.0

This release is mainly about bug fixes and extending our codebase to support replication.

• Dragonfly can now connect as a replica behind Redis master (supports REPLICAOF command)
• Dragonfly can now connect to another Dragonfly instance to form DF->DF replication. This feature is not fully implemented yet but
  it performs the first part, namely "full sync stage". Now we are working on "stable state replication".
• Dragonfly now supports the active-defrag feature. See Introduce active defragmentation #448 for more details.

Huge thanks to all the contributors! ❤️
