[Pki-devel] [PATCH 0044 Don't use settings like HTTP proxy from env vars

The PKIConnection class uses python-requests for HTTPS. The library picks up several settings from environment variables, e.g. HTTP proxy server, certificate bundle with trust anchors and authentication. A proxy can interfere with the Dogtag installer and cause some operations to fail. With session.trust_env = False python-requests no longer inspects the environment and Dogtag has full controll over its connection settings. https://requests.readthedocs.org/en/latest/api/?highlight=trust_env#reque... https://fedorahosted.org/pki/ticket/1733 https://fedorahosted.org/freeipa/ticket/5555
