Assisted installer agent: Unable to pull okd binaries on nodes behind a proxy

Describe the bug

Agent service doesn't start on cluster nodes (booting from agent.iso) because okd-binaries.sh can't pull an okd image

Root cause : HTTPS_PROXY is not set and /etc/profile.d/proxy.sh doesn't exists

As a temp workaround, one can ssh to each node and add export HTTP(S)_PROXY=_proxy_url_ before podman pull line. After that, discovery and installation succeeds

# edit file and restart service
sudo vi /usr/local/bin/okd-binaries.sh ; sudo systemctl restart okd-overlay.service

Don't know if it's related, but if I don't add HTTP(S)_PROXY in okd-configmap.yml, cluster nodes joins discovery without any problem (but installation fails because assisted-installer can't download installation files)
