> In order to be able to do deployments of Kafka that are FIPS 140-2 (https://en.wikipedia.org/wiki/FIPS_140-2) complaint one of the requirements is not to use MD5.
> Kafka is using MD5 to hash message keys in the offset map (SkimpyOffsetMap) used by the log cleaner.
> The idea is to be able to configure this hash algorithm to something allowed by FIPS using a new configuration property.
> The property could be named "log.cleaner.hash.algorithm" with a default value equal to "MD5" and the idea is to use it in the constructor of CleanerConfig.
