Add text to the Create Volume dialog's Type menu

The first value in the "Type" dropdown menu of the Create Volume dialog
was empty. This causes some confusion to the user because there was not
enough information as to why the value was empty or what would happen
when creating a volume with the empty type.

Adding text "No volume type" to the first value of the dropdown menu
explains that there will be no volume type associated with the volume
at creation time.

Remove warnings when generating docs

Sphinx generates a warning about having too few underlines under the
title "ADD_ANGULAR_MODULES". The generated docs are still correct
(title is generated with an underline), so this change only needed
to eliminate the warning messages.

Fix keystone warnings while building docs

When building the documentation via run_tests.sh, doc/source/conf.py
explicitly sets the DJANGO_SETTINGS_MODULE environment variable,
overriding any existing value that it already has. Furthermore, it sets
it to point to a settings file that does not use keystone v3, which
is expected by the tests (and is the source of the warning).  Note that
when running unit tests via run_tests.sh, a different settings file is
supplied which DOES use keystone v3.

Change the doc/source/conf.py to only set DJANGO_SETTINGS_MODULE if it
is not already set.  Change tox.ini and run_tests.sh to set
DJANGO_SETTINGS_MODULE to the same settings file used by the unit tests,
with keystone v3 support.
