Ensure the function `ensureCustomResourceDefinitionsExist` returns when the duration specified in `retryCRDIntervalMax` flag is reached. This works by passing a context to the backoff so that we can timeout with context.WithTimeout. The new (correct) default duration for the flag is 30s to give a bit more time when controller and CRD are created at the same time. Also limit the amount of resources returned by the list calls to 0 to speed up the operations because we only care that the CRD exists.

# This YAML file shows how to deploy the snapshot controller
|
|
|
|
# The snapshot controller implements the control loop for CSI snapshot functionality.
|
|
# It should be installed as part of the base Kubernetes distribution in an appropriate
|
|
# namespace for components implementing base system functionality. For installing with
|
|
# Vanilla Kubernetes, kube-system makes sense for the namespace.
