Clean up features for SIG Node e2e tests

[SergeyKanzhelev]

We use features to indicate the environment that is "not standard" for e2e tests - i.e. requires extra configuration beyond feature gates.

This is uber issue to review sig-node features and clean them up:

1. If the Feature is used to indicate just a "category" of tests - remove it
2. If the Feature is used when FeatureGate must be used - replace with the FeatureGate
3. If the Feature truly indicate a special environment, make sure it is well documented and corresponding test lanes are marked appropriately

Once we clear things up we may decide to pass the Feature as an argument for the test lane (similar to kubernetes/test-infra#35531 idea) and have more automated validation that the test requiring the Feature are only run in the test lane implementing this special environment
