kafka-topics.sh command not honouring --disable-rack-aware property when adding
partitions.
Create topic honours --disable-rack-aware property. Where as alter topic always
honours default rackAwarMode(Enforced) to add partitions.
Steps:
* Start brokers.
0 -> r1, 1 -> r1, 2 -> r2, 3 -> r2
* Create topic _topic1_ with 8 partitions and 2 RF. No partition should have
replicas on same rack brokers. Ex: 0,1 and 2,3 replica should never be created.
Create topic _topic2_ with 8 partitions and 2 RF with --disable-rack-aware.
Partition can have replicas on same rack brokers. Ex: 0,1 and 2,3 replica if
present is acceptable.
* Add 8 more partitions to _topic1._ No newly added partition should have
replicas on same rack brokers. Ex: 0,1 and 2,3 replica should never be created.
* Add 8 more partitions to _topic2_ with --disable-rack-aware_._ Newly added
partition can have replicas on same rack brokers. Ex: 0,1 and 2,3 replica if
present is acceptable. Try repeating this step, no matter what, partitions are
always rack-aware.
