ListSnapshots memory leak

[pwschuurman]

Repro (In GKE):

• Create a VolumeSnapshotContent with a valid snapshotHandle, but which never becomes ready (eg: snapshot creation request fails)
• csi-snapshotter will periodically call ListSnapshots, which has a memory leak when calling GCE.

Problem:

• The nextPageToken should be set at the end of the loop. Currently the loop continues until the client context times out the RPC call. Memory leak here:
  • ListSnapshots:

    gcp-compute-persistent-disk-csi-driver/pkg/gce-cloud-provider/compute/gce-compute.go

    Line 311 in daac2c6

    nextPageToken := "pageToken"

• ListImages:

  gcp-compute-persistent-disk-csi-driver/pkg/gce-cloud-provider/compute/gce-compute.go

  Line 1306 in daac2c6

  nextPageToken := "pageToken"
