BUG@21585 The --help option shows a screen of command options for the ndbd, ndb_mgmd, ndb_mgm

           and other commands related to ndb. For all of these, the help screen contains 
           "Ndb.cfg" string. Now i change the "Ndb.cfg" to "my.cnf" because "Ndb.cfg" is obsolete.


storage/ndb/include/util/ndb_opts.h:
  Change help information from including "Ndb.cfg" to "my.cnf" in the header file.
storage/ndb/test/ndbapi/flexScan.cpp:
  Change help information from including "Ndb.cfg" to "my.cnf".
storage/ndb/tools/ndb_condig.cpp:
  Change help information from including "Ndb.cfg" to "my.cnf".
