This PR is incomplete and can't work as it is:

• missing proxy configuration for underlying k8s
• ele-testhelpers for setting rancher proxy URL is using hardcoded value which can be different in your environment

This PR is incomplete and can't work as it is:

• missing proxy configuration for underlying k8s

Currently, I am working on this to accommodate changes to existing k3s installation.

• ele-testhelpers for setting rancher proxy URL is using hardcoded value which can be different in your environment

This is done.

Only missing piece is the k3s configuration :)

What prevents you to add something like this into install_suite.go when proxy is ON?

cat <<EOF | sudo tee /etc/default/k3s > /dev/null
HTTP_PROXY=http://${proxy_host}
HTTPS_PROXY=http://${proxy_host}
NO_PROXY=127.0.0.0/8,10.0.0.0/8,cattle-system.svc,172.16.0.0/12,192.168.0.0/16,.svc,.cluster.local
EOF

Nothing is stopping me to add this option to K3s, I will add it and update the PR.
