Undesirable LOG in tests output

[Sergey Kraynev]

Heat tests job for py34 passes with strange output:

--- Logging error ---
Traceback (most recent call last):
  File "/usr/lib/python3.4/logging/__init__.py", line 964, in emit
    msg = self.format(record)
  File "/usr/lib/python3.4/logging/__init__.py", line 814, in format
    return fmt.format(record)
  File "/usr/lib/python3.4/logging/__init__.py", line 559, in format
    record.exc_text = self.formatException(record.exc_info)
  File "/usr/lib/python3.4/logging/__init__.py", line 509, in formatException
    traceback.print_exception(ei[0], ei[1], tb, None, sio)
  File "/usr/lib/python3.4/traceback.py", line 173, in print_exception
    for line in _format_exception_iter(etype, value, tb, limit, chain):
  File "/usr/lib/python3.4/traceback.py", line 150, in _format_exception_iter
    for value, tb in values:
  File "/usr/lib/python3.4/traceback.py", line 129, in _iter_chain
    context = exc.__context__
AttributeError: 'NoneType' object has no attribute '__context__'

After investigation, I can say, that it happens only for two tests:

test_delete_in_progress_convergence
test_update_in_progress_convergence

in test_resource module.

It happens only for LOG.exception line. If use another type error, warn, etc it will not report any strange logs, but I don't think, that it's right solution.

    Use LOG.error when no exception handler is used

    There's no need to use LOG.exception here since sys.exc_info()
    results in (None, None, None) and thus would effectively just
    be LOG.error.

    Also, the failure of invoking LOG.exception outside of an
    exception handler is due to a bug in Python3[1]. The fix for
    that is only available in Python3.5.
