ignition: propogate HTTP proxy variables from host to remote
Podman often has to run behind an http/https proxy, often in corporate environments. This proxy may or may not include SSL inspection capabilities, requiring a trusted SSL CA certificate to be added to a system's trust store. Solve this by reading standard proxy variables (HTTP_PROXY HTTPS_PROXY NO_PROXY http_proxy https_proxy no_proxy) and injecting them into the machine at init.
