APEXCORE-634 Apex Platform unable to set unifier attributes for modules
Problem: Unable to set Unifier attributes of output port within modules
Description: When modules are flatten in logical Plan of DAG, only top
level attributes are cloned of OperatorMeta. Unifier attributes are not copied
in PortMapping for output ports.
Solution: Clone the unifier attributes while flattening DAG in logical
Plan.
Testing done for custom application with and without modules also with app
template HDFS to S3 module. Have had debug logs and stack traces to verify the
fix.
One of the snip of logs had set the unifier attribute TIMEOUT_WINDOW_COUNT
to 10 ( i.e 1000 millisec)
**Without fix:**
**<log_snip>**
