Documentation bug - proxy config

[Jonathan Rosser]

- [x] This doc is inaccurate in this way: ______
- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output.

The example global_environment_variables given in "Basic proxy configuration" does not work correctly and repo containers fail to build.

It is necessary to specify proxy_env_url and no_proxy_env, as those variables are consumed directly elsewhere.

See:

https://github.com/openstack/openstack-ansible/blob/master/etc/openstack_deploy/user_variables.yml#L121

The proxy_env_url variable is used in the repo_server role for the configuration of the apt-cacher-ng service. I'm not sure why this conflicts though? Do you have any form of error output which shows the issue?

[Jonathan Rosser (jrosser)]

I don't think it's a conflict, more that the existing docs don't tell
you to set proxy_env_url.
