Code Issues Proposed changes

Remove run_tests.sh wrapper

Browse Source 
The run_tests.sh mechanism for performing operations
is no longer the preferred approach. It is now better
to just run tox. There are also issues with enforcing
upper constraints that may cause test runs to fail.

To get rid of confusion by having two different ways
to run unit tests, flake8 checks, etc., it's probably
better to just remove the run_tests.sh script completely
and direct folks to use tox instead. This way we are all
consistent and there is less concern that changes will
be made to one and not the other.

Manually installing and using the virtualenv
--------------------------------------------
You can manually install the virtual environment instead of having
``run_tests.sh`` do it for you::
You can also manually install the virtual environment::
python tools/install_venv.py
tox -e py27 --notest
or::
tox -e py35 --notest
This will install all of the Python packages listed in the
``requirements.txt`` file into your virtualenv. There will also be some
additional packages (pip, setuptools) that are installed
by the ``tools/install_venv.py`` file into the virtualenv.
``requirements.txt`` file into your virtualenv.
If all goes well, you should get a message something like this::
To activate the Cinder virtualenv you can run::
Cinder development environment setup is complete.
$ source .tox/py27/bin/activate
To activate the Cinder virtualenv for the extent of your current shell session
you can run::
or::
$ source .venv/bin/activate
$ source .tox/py35/bin/activate
To exit your virtualenv, just type::
$ deactivate
Or, if you prefer, you can run commands in the virtualenv on a case by case
basis by running::
$ tools/with_venv.sh <your command>
$ tox -e venv -- <your command>
