Migration work was already done to move controller-runtime from k8s v1.13 to v1.14, however this introduced certain issues.

Unfortunately, workqueue_queue_duration_seconds and workqueue_work_duration_seconds were included in v0.1.10, but were recorded with microsecond values. Moving to k8s v1.14 corrects those values to seconds.

Primarily this change removes the metrics that were deprecated in k8s v1.14, but were never previously included in v0.1 of controller-runtime.

The one metric that was deprecated and is retained is longest_running_processor_microseconds, as it was included in v0.1.10.

pkg/runtime/scheme was supposed to maintain a type alias to make it
easier for people to upgrade and/or interact with projects written
around older versions, but apparently, I forgot to actually leave the
type alias around.  This fixes that.
