Triton inference server metrics is not supported

[antonaleks]

Describe the bug

I can not expose triton metrics in deployment - i put ports dsecribtion at Pod.v1 spec and use Triton implementation, but metrics ports can not be recognized.

Triton server has metrics only on /metrics endpoint, not on /prometheus. May be i can change MLSERVER_METRICS_ENDPOINT env?

To reproduce

1. define model

There are no Metrics endpoint in Deploymnent!
-->

Expected behaviour

Deployment has endpoint with metrics in 8002 port

Environment

• Kubernetes Cluster Version 27.7.1
• Deployed Seldon System Images: [Output of kubectl get --namespace seldon-system deploy seldon-controller-manager -o yaml | grep seldonio]
  value: docker.io/seldonio/seldon-core-executor:1.17.1
  image: docker.io/seldonio/seldon-core-operator:1.17.1

Looks like #5166

i fixed this problem by custom seldon deployment without TRITON_SERVER implementation

But question about TRITON_SERVER implementation is still opened
