[APEXMALHAR-2106] Support multiple streams in StreamMerger
* Added ability to support more than one stream in the operator
Note: I am unclear whether this approach will work if the operator or the
DAG restarts, will the ports be reconnected properly? If not, what mechanism
prevents this?

> To properly implement the Flatten transformation (and other Stream
> combination operations), Apex must support merging data from multiple
> sources. The StreamMerger operator can be improved to merge multiple streams,
> rather than just the two streams it can handle in the present implementation.
