[e2e] update test cases for volume storage class naming changes

[lanfon72]

Which issue(s) this PR fixes:

Issue #1189 (from harvester/harvester#5165)

What this PR does / why we need it:

v1.8.0 introduce the new storage class naming for volume (created with image), it will affect our existing test cases.

Implementation details

1. ADD new volume manager VolManager180 to expand the create function for image_uid
2. ADD new volume model VolumeSpec180 to handle the new argument image_uid
3. ADD new class method VolumeSpec.for_image as the handy method to create volume with image.

Demonstration

imgmgr = "api.images"
volmgr = "api.volumes"
image_info = "dict from image, must contains 'metadata' and 'status'"

# fast way: create the volume as the image size
spec = volmgr.Spec.for_image(image_info)
volmgr.create("volume name", spec)

# old way
spec = volmgr.Spec("volume size, ideally it should >= virtual image size")
image_id = image_info['metadata']['namespace'] + / + image_info['metadata']['name']
volmgr.create("volume name", spec, image_id=image_id, image_uid=image_info['metadata']['uid'])

Caveats

1. Volume manager will support the new image_uid but do nothing in old implementation
2. The new class method for_image will handle the legacy/new storage class name via image_info.status.storageClassName, but the value might be empty if the image was not succeed downloaded. (or other case that the image is not usable)
3. You can still use old way to assign the image_uid to VolumeSpec. (the old way)
