Fix tempest errors

Tempest currently runs for about 1.5 - 2 hours.  I have included a copy of the last output and commented modifications to Jumpgate which allow Tempest get deeper into the tests.  
1) This is the output of the last run.  It skipped one but was able to run 63 with 2 errors and 8 failures.  I am not sure tests were the ones that passed.  There are ~75 tests to run in the whitelist.
Ran 64 tests in 5047.007s

FAILED (SKIP=1, errors=2, failures=8)

2) cancel_jumpgate_instance.sh is the script which cancels jumpgate instances and volumes created during the tempest tests.
