As part of the deployment process, the driver is deployed in a newly created namespace by default. The namespace will be deleted as part of the cleanup process.

Controller-level and node-level deployments will both have priorityClassName set, and the corresponding priority value is close to the maximum possible for user-created PriorityClasses.
