changed the code to read the default lifecycles from multiple files from...

... a folder instead of reading from configurations.xml file

Earlier the governance module was reading the default lifecycle configuration from CARBON_HOME/repository/resources/lifcycles/configurations.xml. I have changed this to read multiple files from the directory "CARBON_HOME/repository/resources/lifcycles/". 
After this changes, if we want to create a new lifecycle, we need to put our configuration file within this directory. Here the configuration file name should be same as the aspect name of the lifecycle.  So when committing this change,  the configuratons.xml file also should be renamed with the aspect name of the lifecycle.
i.e: CARBON_HOME/repository/resources/lifcycles/configurations.xml should be renamed to CARBON_HOME/repository/resources/lifcycles/ApplicationLifecycle.xml
