openstack/nova - nova - OpenDev: Free Software Needs Free Tools

Since moving to bzr, we no longer generate ChangeLog and vcsversion.py
and since commit deb31cb55 we no longer even have the bzr specific code
for generating them. So, let's just remove any references to them.
Change-Id: I4f96b9be48e289f9129ae8e3ad4cbc1b22db07d2

Added a flag to run_tests.sh to allow user to optionally install venv with --no-site-packages.
This fixes bug 880905

Also, add an option to run_tests.sh to skip running pep8. We have a separate
job in Jenkins which runs pep8, so there's no need to spin our wheels on it
during the test run.

Add set -eu to run_tests.sh. This will cause it to fail whenever anything
goes wrong, which is exactly what we want in a test script.
To do this, I had to remove the use of the "let" keyword, which has a bizarre
exit status in bash.
I also removed the "|| exit" after run_tests, which means that this script
will now exit with status 1, not status 0, if run_tests fails.

./run_tests.sh --just-pep8
or
 ./run_tests.sh -p

- if it crashes right away with a short erorr log, print that directly
- allow specifying tests without the nova.tests part

Run pep8 after unit tests in run_tests.sh.
Fix setup.py to be PEP-8 compliant.

Change the argument parsing in run_tests.sh so that we explicitly gather
the arguments that aren't meant for run_tests.sh, and pass them on to
nosetests.
