Problem in gnocchi with devstack behind proxy when executing the pip install command

[Marcus Floriano]

When installing devstack with gnocchi behind a proxy displays error below.

To fix this problem you need to add the option "--proxy http://user:password@proxyserver:port" in the line "++/opt/stack/gnocchi/devstack/plugin.sh:install_gnocchi:391"

++/opt/stack/gnocchi/devstack/plugin.sh:install_gnocchi:388 '[' True == True ']'

++/opt/stack/gnocchi/devstack/plugin.sh:install_gnocchi:391 sudo -H pip install -e '/opt/stack/gnocchi[test,file,mysql,keystone]'

devstack has a function that re-export HTTP_PROXY variables when calling sudo pip install. Unfortunately it can't be used by Gnocchi since the upper-constraint might break it at any point.

So we should probably copy the same mechanism.

Ok, thanks, this is better solution.
