What do you want to work on?

Hello. I'm exploring OpenShell in some of our researched and faced few issues I would like to fix related to Helm validation which prevents invalid or duplicated gateway listener ports from reaching k8s. I'l already forked OpenShell repo to test my changes and they looks promising during tests.

Why this change?

Yet so far OpenShell chart accepts configs that can end-up with an unusable gateway.
