Although running `dnf` from the command line works without explicitly configuring the proxy, because it inherits the environment variables set by PAM on login from the user's shell, the `dnf` Ansible module does not, as it does not inherit those variables. Thus, we need to explicitly configure the `proxy` setting in `dnf.conf` in order to be able to install packages via Ansible. Since `dnf` does not have separate settings for different protocols (e.g. HTTP, HTTPS, FTP), we need a way to specify which of the configured proxies to use if there are multiple. As such, the *useproxy* role will attempt to use the value of the `dnf_proxy` variable, if it is set, falling back to `yum_proxy` and finally `http_proxy`. This should cover most situations without any explicit configuration, but allows flexibility for other cases.
