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) Detailed output of the last run can be found in tempest_output.txt .  It skipped one but was able to run 63 with 2 errors and 8 failures.  I am not sure which 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.  You may need to edit the regex to grep against.  Right now the script uses SoftLayer CLI and deletes all instances which end with jumpgate.com.
I see several lines like this saying T0D0 but not really showing anything to change in that part of the code in the future.  Should it just be a plain comment line:
# returning None makes tempest fail, conditionally returning empty string
