Copy all proxy envs into the VM on each start, this allows for updates without having to recrate the VM. This is implemented via shell script that is passed via ssh to the VM after it is started. With that we now use the same logic for all providers the old fw_cfg logic for qemu has been removed and the WSL code as well which keeps the behavior the same. There is a small risk now because we only update the env via ssh that processes started before will have the old incorrect env but it should really only effect core system processes which likely do not need them anyway. The podman system service should not be started at this point so it should be good enough. It also fixes the broken behavior with SSL_CERT_FILE/SSL_CERT_DIR which were updated on each start which is not correct as the files are only copied with ignition so these should not be updated and just set statically when the VM was created. e2e test has been added to ensure the behavior works as expected.
