Implementing a test suite was impossible outside of the k8s.io/kubernetes/test/e2e/storage/testsuites package because all interfaces and structs used by them were private. As part of revamping the API, genericVolumeTestResource also gets exported because it is useful for other test suites. Because the TestResource interface became obsolete a while ago and isn't used anymore, the new name is just testsuites.VolumeResource. testpatterns.CSIInlineVolume needs special handling in a few places. It can now be used in a test pattern for a test suite that uses a VolumeResource instance.
