Support for Transaction Coordinator

[nicoloboschi]

• New Job that initialize metadata for transactions (create system namespace and topics)
• It depends on broker component and it waits a broker to be available
• The K8s job config (affinity, tolerations...) are coupled with the Broker
• There are two different jobs, one for broker deployment and one for the broker sts (they are the same except for the k8s configs)
• There's a new dictionary inside broker and brokerSts: ´transactionCoordinator´ with ´enabled: false´ and ´initialCount: 16´
• If you configure the broker to initialize the transactions metadata, also the parameter transactionCoordinatorEnabled will be set to true

Note: I haven't verified it with TLS for now
