 * This method also initializes the defined filters configured in HBM/Classes/Packages based on the definedFilterNamesMap. 
 * If definedFilterNamesMap contains 'ALL' as the Filter Name (key) then all defined filters are enabled.
 * <br>
 * This method first obtains the list of all the defined filters from the SessionFactory in the passes Session object. 
 * It then just iterates through the filter list and sets the group names and the application name parameter. 
 * 
 * @param groupNames The names of the groups which are invoking the query
 * @param session The Hibernate Session initialized to execute this query
 * @param authorizationManager The CSM AuthorizationManager instance for this application
 * @param definedFilterNamesMap - Map of defined Filter Names and string value ( enable / disable ) to indicate that the filter should be enabled of disabled.<br>.
