2 items for all items

2 partition for all DI kafka topics:

Examples:

delete old topic
# ./kafka-topics.sh --bootstrap-server=<kafka-ip>:9092 --delete --topic perf-eks-folijet.Default.fs09000000.DI_ERROR

recreate topic with "--partitions 2 --replication-factor 1"
# ./kafka-topics.sh --bootstrap-server=<kafka-ip>:9092 --create --topic perf-eks-folijet.Default.fs09000000.DI_ERROR --partitions 2 --replication-factor 1
WARNING: Due to limitations in metric names, topics with a period ('.') or underscore ('_') could collide. To avoid issues it is best to use either, but not both.
Created topic perf-eks-folijet.Default.fs09000000.DI_ERROR.
