load_paste_app Doesn't provide a traceback

[Jason Kölker]

  In quantum/common/config.py

  316 try:
  317 app = deploy.loadapp("config:%s" % conf_file, name=app_name)
  318 except (LookupError, ImportError), e:
  319 raise RuntimeError("Unable to load %(app_name)s from "
  320 "configuration file %(conf_file)s."
  321 "\nGot: %(e)r" % locals())
  322 return conf, app

Logging of 'e' in a string causes only the __str__ representation to be reported. This makes it almost impossible to track down where the issue is coming from. LOG.exception should be used so the traceback is logged.
