Fails to start a server providing the configuration file

[Victor Morales]

Using "glance-control api start etc/glance-api.conf" or "glance-control registry start etc/glance-registry.conf", it's resulting in the following error:

Traceback (most recent call last):
  File "/home/vagrant/glance/.venv/bin/glance-control", line 10, in <module>
    sys.exit(main())
  File "/home/vagrant/glance/glance/cmd/control.py", line 354, in main
    pid = do_start('Start', *args)
  File "/home/vagrant/glance/glance/cmd/control.py", line 199, in do_start
    return launch(pid_file, conf_file, CONF.capture_output, CONF.await_child)
  File "/home/vagrant/glance/glance/cmd/control.py", line 163, in launch
    msg += 'with %s' % conf_file
  File "/home/vagrant/glance/.venv/local/lib/python2.7/site-packages/oslo/i18n/_message.py", line 154, in __add__
    raise TypeError(msg)
TypeError

This is because the variable "msg" is an instance of "oslo.i18n._message.Message" which not support concatenation.

    Start server message changed

    The way that the user message was generated when it's launched a
    server providing a configuration file was causing an error. This is
    because the Message class doesn't support concatenation.
