UPSTREAM: <drop>: Disable volume group snapshot tests

Temporarily disable volume group snapshot (VGS) tests. We need to rebase the
external-snapshotter that updates VGS API in an incompatible way (v1beta1
-> v1beta2 without automatic conversion). The API is TechPreviewNoUpgrade,
so its breakage won't affect any customer.

We need to update all components that provide or use the API while the
tests are off, they would fail spectacularly.
