Set up global proxy environment variables from user variable

[Ian Cordasco]

For users deploying from behind a proxy, pip (and requests) needs to know what those proxies are. It would be useful to have a variable that can be configured to automatically configure the HTTP_PROXY and HTTPS_PROXY environment variables. pip and the python clients will respect these variables as necessary. Defining these on the hosts and containers should be a common task only when the user variable is defined.

[Ian Cordasco (icordasc)]

We should also, at the same time, calculate a NO_PROXY environment variable. We should probably add to that, the container network CIDR, and a few other IPs/hosts (localhost, etc) that we know we won't need to talk to the proxy for since they're internal only.

    Handle proxies through environment variables

    When running os-ansible-deployment on a cluster siting behind a proxy,
    users may need to set up special variables for proxies so that pip, and
    the services all work as expected.

The lower case variants of http_proxy and https_proxy also need to be added to the user_variables.yml file.

I encountered an issue with a customer yesterday where any Ansible module using the get_url core module would not honor the upper case HTTP_PROXY and HTTPS_PROXY environment variables. Once the lower case variants were added, the Ansible tasks completed.

This issue was fixed in the openstack/openstack-ansible 11.2.14 release.
