Rack-Aware replica assignment option
Adding a rack-id to kafka config. This rack-id can be used during replica
assignment by using the max-rack-replication argument in the admin scripts
(create topic, etc.). By default the original replication assignment algorithm
is used because max-rack-replication defaults to -1. max-rack-replication > -1
is not honored if you are doing manual replica assignment (preffered).
If this looks good I can add some test cases specific to the rack-aware
assignment.
