Created a make_web_conf command.

The current wsgi does not support virtualenvs (in some distributions, the
dependencies may conflict with the distribution's python packages/dependencies
and would require a virtualenv even in production).
Also, making an apache web configuration is not always trivial especialy
with ssl.
This "make_web_conf" command creates a wsgi with automatic virtualenvironment
detection (if there is a virtualenvironment), and creates an apache
(normal or ssl) configuration

TODO(ygbo)::

    - add nginx support to generate nginx configuration files.
    - add gunicorn support.
    - add uwsgi support.

setting the initial value to IPv4.

Not display loading image for shelved instances

If, any of the instances are shelved through CLI
those instances status are displayed as shelved offloaded
with a loading image.
Displaying the loading image for this status are not correct.
Displaying the loading image is removed for
the shelved offloaded status.
This problem is reported and fixed in #1318558 but this fix is
working only for rescue not for shelved offloaded.
Now it is fixed for shelved offloaded also.
