kubernetes-client: HasMetadataOperation.periodicWatchUntilReady is broken

Our call to HasMetadataOperation.waitUntilReady never returns. A stacktrace suggests that the thread is stuck awaiting the latch at https://github.com/fabric8io/kubernetes-client/blob/5f5d1697839b0b220bf400133a4dbe65a56f797d/kubernetes-client/src/main/java/io/fabric8/kubernetes/client/dsl/base/HasMetadataOperation.java#L192

I believe the cause is https://github.com/fabric8io/kubernetes-client/pull/1451 which changes millisecond values into nanoseconds, but the interval value used in the above line is still treated as a milliseconds value, resulting in a huge wait time.
