[RHOAIENG-4191] - odh-model-controller should tolerate missing Authorino

[spolti]

This commit allows to run ODH without Authorino when KServe is Removed.

Description

How Has This Been Tested?

• Install the ODH Operator 2.8 through Operator Catalog.
• Create Default DSCI
• Create a DSC with the following content (KServe -> servinng - disabled):

kind: DataScienceCluster
apiVersion: datasciencecluster.opendatahub.io/v1
metadata:
  labels:
    app.kubernetes.io/created-by: opendatahub-operator
    app.kubernetes.io/instance: default
    app.kubernetes.io/managed-by: kustomize
    app.kubernetes.io/name: datasciencecluster
    app.kubernetes.io/part-of: opendatahub-operator
  name: default-dsc
spec:
  components:
    codeflare:
      managementState: Removed
    kserve:

      serving:
        ingressGateway:
          certificate:
            type: SelfSigned
        managementState: Removed

            sourcePath: ''
            uri: >-
              https://github.com/spolti/odh-model-controller/tarball/RHOAIENG-4191-test
      managementState: Managed
    datasciencepipelines:
      managementState: Removed

• Note that the KServe - serving component is disabled, it should not log any error, instead, this message should be logged:

controllers.InferenceService    kserve service mesh component is enabled, Authorino is required.

• Next step, update the DCS setting KServe/serving to Managed, install the Service Mesh Operator and don't install the Authorino operator, and watch the logs for the error:

2024-03-06T19:25:57Z	INFO	controllers.InferenceService	kserve component is enabled, Authorino is required

Almost! More feedback:
The DSC can be:

apiVersion: datasciencecluster.opendatahub.io/v1
kind: DataScienceCluster
metadata:
  name: default-dsc
spec:
  components:
    kserve: 
      managementState: "Removed",
      serving: 
        ingressGateway: 
          certificate: 
            type: SelfSigned
        name: "knative-serving",
        managementState: "Managed"

Notice kserve.managementState is Removed while serving.managementState is Managed. If KServe is removed, I think odh-model-controller don't need to care about authorino.

So, turns out we would need to check kserve.managementState == Managed && serving.managementState != Removed, to require authorino here.

I think I'm bad at explaining stuff.

[spolti]

both enabled, right.

okay.
