Added unit test for NodeLabelJDBCImpl. Fixes bug NMS-7170 and should
prevent problems like NMS-7156 in the future.
Refactored NodeLabel API to remove JDBC-specific types.
Fixed some compile errors after the NodeLabel refactor.
Switched code over to use PathOutageManagerDaoImpl. Fixed some DISTINCT
problems in the PathOutageManagerDaoImpl code. Fixed ordering of the results
on showNodes.jsp to fix issue NMS-7157.
