Fixes LP Bug#899383 - Cleanup config file search
Cleans up a bunch of configuration-related errors
when trying to run tempest out of the box with a
simple call to:
$> nosetests storm
* Raises a sensible error if the config file cannot be found
* Makes it possible to set the config file directory and
config file name via environment variables
* Removes unnecessary calls to create storm.config.StormConfig()
and share a configuration object by passing the openstack.Manager's
config object with the various rest client objects
* Updates the README to show how to make a config file and run
the tests in tempest
