Support for Multiple NGF Gateways

[mpstefan]

As a NGF user with a large Kubernetes Cluster
I want to separate my traffic using multiple NGF Gateways
So that I can have separate pieces of infrastructure manage different types of traffic in my environment.

Acceptance

• When the user defines more than one Gateway object in their environment, a corresponding NGF data plane is created.

Would this separate the control and data plane then? This could be a major feature for us as nginx-ingress does not separate the control and data plane leading to us deploying nginx-ingress multiple times per cluster.

@coolbry95 It is definitely going to be much easier when they are, and so, yes, we'll be looking at that separation in 1.3 as well.

[mpstefan]

Moving milestone to match data and control plane separation. Design should commence during 1.3 development time.

[mpstefan]

Moving to 2.0, as the data/control plane separation will be a major release.

Another issue I am trying to solve by having multiple Gateway is to separate SSL certificate configuration. With single Gateway certificate/https termination defined in single place, and will have to be managed by central admin team. If Gateway per app, Dev/Projects can define Gateway and their SSL requirements and Certificate manager will provision as required.
