When global_environment_variables is set in user_variables.yml, this installs environment settings in /etc/environment on all hosts and containers. These remain in place after deployment is complete. This patch adds a similar variable deployment_environment_variables that defines environment strings applied only while the playbooks are running. They leave nothing behind on the hosts or containers. This may be used, for example, for proxy settings required only during deployment. A simpler no_proxy setting is adequate during deployment, so this provides a workaround to Bug #1691749. Change-Id: Ia15d2133c6749fa9496bbf9359b8bf075742d60e Related-Bug: #1691749
