[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
