Argument of exception.GlanceConnectionFailed is incorrect in glance.py

[Kiyohiro Adachi]

cinder/cinder/image/glance.py is used as follows.

  raise exception.GlanceConnectionFailed(netloc=netloc,
                                         reason=str(e))

'netloc' is always ignored.

    Fixes call GlanceConnectionFailed in invalid ARG

    A mapping key of 'netloc' is always ignored. Thus information in
    'netloc' is lost. But because it is included in 'error_msg', I remove
    'netloc=netloc'.
