[haproxy-unified-gateway] Creating Gateway on low port crashes HUG installed with default values

[lrenjic]

HUP crashes with cannot bind socket (Permission denied) if you create Gateway resource with low port.

Need to set controller.unprivileged: false to be able to create Gateway resource on low ports.

@lrenjic thx for reporting this, true, we need to be more resilient.

this is something w need to do in HUG, not in helm charts.

we will do condition Programmed=False for port < 1024 in unprivileged mode + document the limitation.
there are some options we are also exploring, but not all type of deployments will benefit.

+ we are looking can Service port-mapping approach help with this, (we already know it can't in all types of deployment)
