Bug Report

What did you do?

Check a project where I have the CRD only to share status across the components and without spec defined

What did you expect to see?

Not fail because is missing spec
Not warning because is missing the examples for an API that does not have specs

Possible Solution

The following suggestion should only appear only when a spec is provided

"suggestions": [
              "Warning: Value binding.operators.coreos.com/v1alpha1, Kind=BindableKinds: provided API should have an example annotation"
            ]

We ought to not raise the error: https://github.com/operator-framework/operator-sdk/blob/master/internal/scorecard/tests/basic.go#L49-L60
