[Docs]: Integration and E2E tests have no documented cluster prerequisites or setup instructions

Documentation Type

Add missing documentation

Location

docs/development.md

Description

Integration tests (`//go:build integration`) and E2E tests (`//go:build e2e`) require a live OpenShift cluster with KubeVirt/CNV installed. While `docs/development.md` mentions build tags, there is no documentation on:

• Minimum cluster requirements (OpenShift version, CNV version)
• Required cluster state (operators installed, storage classes available)
• How to configure kubeconfig for test execution
• Expected test runtime or resource consumption
• How to run integration tests in isolation vs full E2E

The E2E suite's `BeforeSuite` builds the binary but cluster setup is entirely undocumented.

Suggested Content

Add a "Cluster Prerequisites" section to `docs/development.md` covering:

• Minimum OpenShift version and CNV operator version
• Required storage classes and operators
• Kubeconfig setup instructions
• Example commands for running integration vs E2E tests separately
• Expected resource consumption and test runtime estimates

Severity: Low

Files:

• `docs/development.md` — testing section lacks cluster setup details
• `tests/e2e/e2e_suite_test.go` — BeforeSuite assumes cluster access
