HostNetwork media mode

HostNetwork avoids Kubernetes Service NAT for media but binds RTPengine ports directly on selected nodes. The cluster operator must handle node selection, public addresses, firewall rules, and port conflicts.

Use this mode when media packets need to land directly on selected Kubernetes nodes instead of passing through a Service. It can be useful in environments where UDP Service behavior is hard to control, but it moves more responsibility to node placement and firewall configuration.

Start with LoadBalancer networking unless you already know Service NAT is the wrong fit for your cluster.
