WSME 0.5b5 was updated to return more accurate response status codes. we need to fix our unit tests to accept them.

secondary issue is that when we pass in translatable text to wsme.exc.ClientSideError(), it implodes.

in wsme, https://github.com/stackforge/wsme/blob/master/wsme/exc.py#L15

it checks for type which appears to be unicode but is really <class 'ceilometer.openstack.common.gettextutils.Message'>. when it tries to convert gettexutils.Message to unicode six.u(), it breaks.
