[OCPERT-210] Add OpenShift Tests Extension (OTE) integration by using the automated migration OTE tool

[ming1013]

Tested by:

$ ./cmd/extension/cloud-credential-operator-tests-ext list | grep -F '"name": "[sig-' |wc -l
16

Part of automated migration OTE tool log:

What Was Created

1. Extension Binary: cmd/extension/main.go - Successfully builds to a 315MB binary
2. Test Module: test/e2e/go.mod - Separate module with OTE dependencies
3. Testdata Infrastructure: test/testdata/fixtures.go - Wrapper for accessing test fixtures
4. Build System: Updated Makefiles with tests-ext-build target
5. Module Configuration: Root and test go.mod files properly configured with replace directives

Test Files Migrated

• 4 test files copied from openshift-tests-private
• 1 testdata file (credentials_request.yaml)
• All FixturePath calls automatically updated
• Imports automatically cleaned up

Build Verification

✅ Extension binary builds successfully
✅ Binary executes and shows help
✅ Suite registered: openshift/cloud-credential-operator/tests

The tests will be discovered and run when the extension is used within the OpenShift testing
infrastructure.

@ming1013 Thanks!
As discussed, I will submit the create separate Go module change as a separate PR. After the create separate Go module PR is merged, we can re-run the tool and update this PR accordingly.

[rioliu-rh]

this Makefile should not be here, for multi-modules strategy solution, test extension resources should be compiled via root Makefile

[rioliu-rh]

this file only contains test dependencies. it won't be conflict with operator product code

[rioliu-rh]

Same concern like router operator, required changes (test-ext compress and cp) in root Makefile is missed.
