Review request for Flume.


Repository: flume-git


Description
-------

This feature is useful for anyone who needs greater control of which partitions 
are being written to - normally in a situation where multiple Flume agents are 
being deployed in order to horizontally scale, or alternatively if there is a 
scenario where there is a skew in data that might lead to one or more 
partitions hotspotting.
We also have the ability to specify custom partitions on to the Kafka Producer 
itself using the kafka.* configuration properties.

The Kafka Producer provides the ability to set the partition ID using the 
following constructor 
(https://kafka.apache.org/090/javadoc/org/apache/kafka/clients/producer/ProducerRecord.html#ProducerRecord%28java.lang.String,%20java.lang.Integer,%20K,%20V%29
 ), this is just a matter of providing the option to use this constructor.

This is specified in one of two ways: either via the staticPartition 
configuration property, which means that every message goes to the specified 
partition, or via the partitionHeader configuration property, which directs the 
implementation to retrieve the partitionId from one of the event headers.
