> ZipAggregationStrategy does not preserve any headers from the aggregated exchanges. 
This makes it difficult to do something like name the output zip file based on the correlation
key:
> {code:xml}
>     <from uri="direct:input"/>
>     <aggregate strategyRef="zipStrategy" eagerCheckCompletion="true">
>       <correlationExpression>
>         <simple>${header[batchId]}</simple>
>       </correlationExpression>
>       <completionSize>
>         <simple>${header[batchSize]}</simple>
>       </completionSize>
>       <setHeader headerName="CamelFileName">
>         <simple>batch-${header[batchId]}.zip</simple>
>       </setHeader>
>       <to uri="direct:output"/>
>     </aggregate>
> {code}
> This behavior is inconsistent with other existing AggregationStrategies, including AggregationStrategyBeanAdapter,
FlexibleAggregationStrategy, UseLatestAggregationStrategy, and UseOriginalAggregationStrategy,
which all use the first exchange received (or a copy of it) to initialize the aggregated exchange,
hence preserving headers and properties, including those which may used to determine the correlation
of related exchanges.
