Hybrid gateways - Update Gateway Controller Provisioning Logic

[sandromodarelli]

Problem Statement

To provision a Gateway correctly we need to provision a Konnect controlplane and a local DataPlane. Currently the gateway controller is not handling the provisioning of Konnect controlplanes.

Proposed Solution

Design doc ref: https://docs.google.com/document/d/1TlH7z2AQSvVvdIgU_osxRuZDTvX4E-6zuIxLBcPhWeg/edit?tab=t.0#heading=h.urfn7ys34vi7

The Gateway controller orchestrates the creation of all components required for a Konnect hybrid deployment based on the configuration provided.

The Gateway controller's reconciliation loop will be updated:

• Check if the referenced GatewayClass's parametersRef points to a GatewayConfiguration with the .spec.konnect.APIAuthConfiguration field set.
• If so, provision the following resources, setting the Gateway as their owner:
  • A KonnectAPIAuthConfiguration resource. The .spec of this resource will be populated from the GatewayConfiguration.
  • A KonnectGatewayControlPlane resource to link the KonnectAPIAuthConfiguration.
  • A KonnectExtension resource to link the KonnectGatewayControlPlane.
  • A DataPlane resource, which will be configured via the KonnectExtension to connect to Konnect.

Additional Information

Acceptance Criteria

• Documentation is updated with this new feature / enhancement
• Tests are added for this feature / enhancement
• Helm chart is updated to work with this feature / enhancement
• As a user, I can create a Gateway with a GatewayClass who points to a GatewayConfiguration with a konnect auth ref
• For each Gateway operator will create and reconcile a KonnectAPIAuthConfiguration, a KonnectGatewayControlPlane, a KonnectExtension and a DataPlane
• the KonnectAPIAuthConfiguration will have specs coming from spec.konnect.APIAuthConfiguration of the GatewayConfiguration
• the KonnectGatewayControlPlane will have specs coming from spec.konnect.gatewayControlPlaneOptions of the GatewayConfiguration
