Stages](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-166)

   - Attaching NodeNamesProperty to source stages makes scheduling source tasks 
virtually impossible, if the assigned node does not have the corresponding 
source split. This PR prevents NodeNameAssignmentPass not to assign node names 
on source stages.
   
   **Minor changes to note:**
   - N/A
   
   **Tests for the changes:**
   - N/A
   
   **Other comments:**
   - Integration tests on distributed environment is desired.
