easy_install of pbr fails during devtest.sh run behind http_proxy

[Steven DuChene]

Our tripleo test systems are in a data center where access to outside world through http or https has to pass through a proxy. When we run devtest.sh on a system in this environment and it gets to the image build but fails when easy_install tries to pull pbr.
To duplicate this on a system behind a proxy and where the following sorts of environment varaibles are set:

http_proxy=http://10.22.117.147:8080
https_proxy=http://10.22.117.147:8080
no_proxy=192.0.2.0/24,15.126.28.128/27

and a pypi mirror is setup on the 15.126.28.128 network. a PYPI_MIRROR_URL=http://15.126.28.132/pypi/mirror is set that points at that mirror. Confirming the pbr module is present in that mirror:

# find ~opsauto/.cache/image-create/pypi/ -name 'pbr*'
/home/opsauto/.cache/image-create/pypi/download/projects/requirements/tests/files/pbr_setup.cfg
/home/opsauto/.cache/image-create/pypi/download/wheelhouse/pbr-0.6-py2.py3-none-any.whl
/home/opsauto/.cache/image-create/pypi/mirror/Ubuntu-13.10/pbr
/home/opsauto/.cache/image-create/pypi/mirror/Ubuntu-13.10/pbr/pbr-0.6-py2.py3-none-any.whl
/home/opsauto/.cache/image-create/pypi/mirror/pbr
/home/opsauto/.cache/image-create/pypi/mirror/pbr/pbr-0.6.tar.gz

Then prior to running "devtest.sh --trash-my-machine" do "export break=before-install"

Then in the shell where the break occurs do the following steps:

cd /tmp/in_target.d/install.d/
./00-baseline-environment
./00-ccache
./01-install-pip
rm -rf /opt/stack/venvs/os-refresh-config
virtualenv --setuptools /opt/stack/venvs/os-refresh-config
/opt/stack/venvs/os-refresh-config/bin/pip install -U pip
/opt/stack/venvs/os-refresh-config/bin/pip install -U 'setuptools>=1.0'
/opt/stack/venvs/os-refresh-config/bin/easy_install pbr

I have attached a log file output of:

strace -o /tmp/pbr-fail.log -s 512 /opt/stack/venvs/os-refresh-config/bin/easy_install pbr

    Explicitly install pbr via pip

    When a pypi mirror is used with certain conditions installing pbr as a
    dependency fails. This is a temporary fix until the underlying cause
    is resolved.

    This is also required for a wheels based pip mirror to work.
