    [APEXMALHAR-2106] Support multiple streams in StreamMerger

    * Created a module which creates a binary tree of StreamMerger operators to support merging
multiple streams
    * StreamMerger operators are presently allocated as CONTAINER_LOCAL. I would like for
them to be THREAD_LOCAL but I was getting the following error when attempting this:
    ```
    Caused by: javax.validation.ValidationException: Locality THREAD_LOCAL invalid for operator
OperatorMeta{name=Merger_Tier_0_#_0, operator=StreamMerger{name=null}, attributes={}} with
multiple input streams as they origin from different owner OIO operators
    ```
    
    * An example application is included

    Created a module to merge multiple streams into a single stream. Created a test application
demonstrating this in action. Still need to add more tests.
    
    Fixed error with attempting to use odd number of input streams. Input ports for StreamMerger
are now optional.
    
    Dramatically simplified implementation by replacing manual tier creation with a queue
of unconnected ports.
    
    Updated locality settings.
    
    Added test to count number of tuples received at output and test equality against all
tuples sent across all merged streams.
    
    Added explicit check for values.
    
    Changes to pom.
    
    Restored pom
