• Add PVC as storage option for LM-Eval results #325

This PR adds support for PVC has output storage for LM-Eval jobs. It supports two modes, managed PVC and existing PVC.

Managed PVC

A PVC can be specified in the LMEvalJob as

apiVersion: trustyai.opendatahub.io/v1alpha1
kind: LMEvalJob
spec:
  outputs:
    pvcManaged:
      size: 5Gi

The PVC will be created and managed by the operator, named <LMEvalJob name>-pvc. The only supported configuration at the moment is size.

Existing PVC

An existing PVC can be passed to the LM-Eval job using a PVC name, e.g.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

apiVersion: trustyai.opendatahub.io/v1alpha1
kind: LMEvalJob
spec:
  outputs:
    pvcName: my-pvc

This PVC will not be managed by the operator.
If both managed and existing PVC are specified, the operator will prefer the managed configuration and ignore the existing PVC one.
