ignition: propagate proxy settings from a host into a vm
Set proxy settings (such as `HTTP_PROXY`, and others)
for the whole guest OS with setting up `DefaultEnvironment`
with a `systemd` configuration file `default-env.conf`,
a `profile.d` scenario file - `default-env.sh` and
a `environment.d` configuration file `default-env.conf`
The **actual** environment variables are read by podman
at a start, then they are encrypted with base64 into
a single string and after are provided into a VM through
QEMU Firmware Configuration (fw_cfg) Device
Inside a VM a systemd service `envset-fwcfg.service`
reads the providead encrypted string from fw_cfg, decrypts
and then adds to the files
- `/etc/systemd/system.conf.d/default-env.conf`
- `/etc/profile.d/default-env.sh`
- `/etc/environment.d/default-env.conf`
At the end this service execute `systemctl daemon-reload`
to propagate new variables for systemd manager
[NO NEW TESTS NEEDED]
Closes #13168
