fix: wait for DSC v2 API and add DB migration for MLflow deploy

[Gkrumbach07]

Summary

• Fixes the deploy-rhoai-mlflow GHA job that's still failing after fix: wait for DataScienceCluster CRD before applying DSC #1187
• The CRD wait was checking for CRD existence (v1 was already there), but the DSC manifest uses v2 which gets registered later
• Now waits for v2 to appear in oc api-resources before applying
• Also includes: MLflow replicas set to 1, DB migration step for existing PostgreSQL instances

Root cause

The RHOAI operator registers the DataScienceCluster CRD with v1 first, then updates it to include v2. The previous wait found v1 and proceeded, but the datasciencecluster.opendatahub.io/v2 DSC manifest failed because v2 wasn't served yet.

Test plan

• Re-run the deploy-rhoai-mlflow job and verify it passes
• Verify the v2 API wait step logs show it waiting then succeeding

📝 Walkthrough

Walkthrough

Two deployment workflow files were updated to change readiness verification for the DataScienceCluster API. The deployment wait steps now check for v2 API availability using oc api-resources and grep filtering instead of checking for CRD registration status.

Changes

Cohort / File(s)	Summary
Deployment Readiness Checks .github/workflows/components-build-deploy.yml, .github/workflows/prod-release-deploy.yaml	Updated deployment readiness verification from oc get crd datascienceclusters.datasciencecluster.opendatahub.io to oc api-resources --api-group=datasciencecluster.opendatahub.io | grep v2. Log messages and timeout errors updated from "CRD" to "v2 API" terminology.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	Title follows Conventional Commits format (fix: scope description) and accurately reflects the main change of updating the deployment wait step from CRD v1 to v2 API checking.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Performance And Algorithmic Complexity	✅ Passed	Workflow changes introduce no performance regressions; polling loops are bounded (600s timeout) with explicit breaks, K8s API calls are lightweight, and grep performs simple substring matching without expensive operations.
Security And Secret Handling	✅ Passed	Workflow changes maintain security best practices: secrets properly masked via GitHub Actions, v2 API wait logic uses hardcoded commands with no injection vectors, database operations use safe hardcoded SQL, no sensitive data exposed.
Kubernetes Resource Safety	✅ Passed	PR modifies only GitHub Actions workflows, not Kubernetes manifests. Kubernetes Resource Safety check is not applicable.
