have been deprecated and will be removed in a future release.  Callers should switch to using `wait.PollUntilContextCancel`, `wait.PollUntilContextTimeout`, or `wait.ExponentialBackoffWithContext` as appropriate.
  
  `PollWithContext(Cancel|Deadline)` will no longer return `ErrWaitTimeout` - use the `Interrupted(error) bool` helper to replace checks for `err == ErrWaitTimeout`, or compare specifically to context errors as needed. A future release will make the `ErrWaitTimeout` error...
