GMPLS update - 72: optimizing custom explicit-path parameter entries

Updated #GMPLS #custom #explicit-path #parameter agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #explicit-path entry based #indexing. This will access the custom explicit-path entries by using the #native #indexing. This removes references to the custom explicit-path indexing used earlier. The custom explicit-path parameter entries has been embedded in the standard explicit-path entries. The custom explicit-path parameter entries holds the #attributes like #hop-forward-label and #hop-reverse-label.
