Reduce scope of testing for test-helm-chart

[torredil]

What is this PR about? / Why do we need it?

• Currently, we run the entire External.Storage e2e suite when testing Helm chart changes / upgrades -- overkill. This PR significantly reduces the number of tests we run to a select few that still cover all the functionality:

  • Kubernetes e2e suite: [It] External Storage [Driver: ebs.csi.aws.com] [Testpattern: Dynamic PV (default fs)] volumes should store data
  • Kubernetes e2e suite: [It] External Storage [Driver: ebs.csi.aws.com] [Testpattern: Dynamic PV (delayed binding)] topology should provision a volume and schedule a pod with AllowedTopologies
  • Kubernetes e2e suite: [It] External Storage [Driver: ebs.csi.aws.com] [Testpattern: Dynamic PV (block volmode)(allowExpansion)] volume-expand Verify if offline PVC expansion works
  • Kubernetes e2e suite: [It] External Storage [Driver: ebs.csi.aws.com] [Testpattern: Dynamic PV (default fs)(allowExpansion)] volume-expand should resize volume when PVC is edited while pod is using it
  • Kubernetes e2e suite: [It] External Storage [Driver: ebs.csi.aws.com] [Testpattern: Dynamic PV (default fs)] volumeIO should write files of various sizes, verify size, validate content [Slow]
  • Kubernetes e2e suite: [It] External Storage [Driver: ebs.csi.aws.com] [Testpattern: Dynamic Snapshot (delete policy)] snapshottable[Feature:VolumeSnapshotDataSource] volume snapshot controller should check snapshot fields, check restore correctly works after modifying source data, check deletion (persistent)

• Only run snapshot tests if CRDs detected.

• closes Helm test times out post install #1522
