Add support for API Gateway (alternative to ingress-nginx) #5
Description
Currently, the Helm chart is tied to ingress-nginx for external access. With ingress-nginx becoming less popular and API Gateways (like Kong, Traefik, or cloud-native gateways) gaining adoption, adding support for API Gateway would provide more flexibility.
Proposal
Add support for API Gateway integration:
- Support for Kong Gateway
- Support for Traefik Gateway API
- Support for cloud provider gateways (AWS API Gateway, GCP Cloud Endpoints)
- Abstract ingress configuration to support both traditional ingress and Gateway API
This would allow users to choose their preferred traffic management solution.
