Change location of data/log files

[Klaus-42-root]

Issue with change the location for log files.
I assumed that it could be done with something like this in the inventory file.

kafka_controller:
  hosts:
    host1.dmz23.local:
    host2.dmz23.local:
    host3.dmz23.local:
  vars:
    kafka_controller_custom_properties:
      log.dirs: "/data/kafka/data"

kafka_controller:
  hosts:
    host4.dmz23.local:
    host5.dmz23.local:
    host6.dmz23.local:
  vars:
    kafka_broker_custom_properties:
      log.dirs: "/data/kafka/data"

But the ansible script failed when creating the kafka broker. Because it can not locate the cluster id of the controller (the meta.properties has a wrong cluster.id)

The issue are in the file "roles/kafka_broker/tasks/get_meta_properties.yml" where the variable kafka_controller_final_properties['log.dirs'] are resolved in the wrong scope.

I found a work around - by moving the kafka_controller_custom_properties up as a global variable - but that is a bit backward, and I wasted quite a bit of time find that issue. Note if the each kafka_controller have individual file locations, this workaround will never work.

Tested with version 7.6
