Adds the distributed cross data center (DC-DR) API surface to Kafka, mirroring the Postgres and MongoDB DC-DR types: - spec.distributed and spec.podPlacementPolicy on KafkaSpec, so one Kafka CR expands into one self-contained Kafka cluster per Member data center. - status.disasterRecovery (KafkaDisasterRecoveryStatus, KafkaDCStatus, KafkaDRPhase) reporting the active DC, per DC broker health, cross-DC MirrorMaker 2 mirror lag in milliseconds, and the DR phase. - Per data center dataCenters on KafkaHorizontalScaling ops, so each DC's local Kafka cluster is scaled independently. Hand-spliced deepcopy and the spec and ops CRD fields. Full CRD and openapi regeneration is left to make gen in CI. Signed-off-by: Tamal Saha <tamal@appscode.com>
