    [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?

    Initial implementation of a Stream merger operator that can handle more
    than two input streams. Updated test cases

> 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.
