Promote VolumeGroupSnapshots to GA

[jsafrane]

Promote the gate to GA.

Starting as a draft to avoid surprises. Code was merged a long time ago, the last cleanup was merged today.

• E2e tests that run in all regular e2e parallel should have enough coverage.
• Some e2e tests are serial and thus may miss coverage, sometimes by one.
