#### Description of PR Add Kafka 2.5 Processors set (NIFI-7522), in order to : * Have the last fixes from Kafka * Use the static Membership Consumers (to reduce rebalancing) It's a copy/paste from Kafka 2.0 processors, without new feature. Notes : - Kafka 2.5 use scala 2.12, and not 2.11 anymore. - Kafka 2.6 is late, maybe the next NIFI step could be Kafka 3.x. - To reduce the convenient store size, the idea is to put in profile the 0.9/0.10 processors (PR created by MikeThomsen : https://github.com/apache/nif [NIFI-7522 - Template-Test.zip](https://github.com/apache/nifi/files/4864666/NIFI-7522.-.Template-Test.zip) i/pull/4364) - A 1st draft PR with some comments was there : https://github.com/apache/nifi/pull/4346 (closed because i PR from my master and not a dedicated branch). ### For all changes: - [x] Is there a JIRA ticket associated with this PR?

The 3 consumers have a group.instance.id 01 02 03 and a session.timeout.ms of 10minutes. **Results :** * The consumer consumes (like in 2.0) * The kafka server log show the join of the static consumer : "Static member Some(01) of group CG with unknown member id rejoins". ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
