ndb api test case for bug 29501

storage/ndb/test/ndbapi/testDict.cpp:
  Added test for Bug#29501. Tested on both code without patch and code with patch. DN fails on code w/o and passed for code w/. Also includes new helper functions runWaitStarted and DropDDObjects. Along with these helper function I have included a test for DropDDObjects. I did find a case where lgman fails on the restarting DN with corrupt fs error. I will file a new bug report and test case for that.
