Matt Moore e4ac97c252 Update our dependency on K8s libs to 1.15.3 (#686) 
With a minimum K8s version of 1.14 (starting in 0.10), 1.15.3 puts us in the center of the +/-1 version window of support.

Matt Moore ecb98001f2 Implement workqueue.MetricsProvider (#678) 
The kubernetes workqueue provides a facility for collecting metrics by registering a workqueue.MetricsProvider
via workqueue.SetProvider.

This change implements that interface to expose the workqueue metrics into opencensus.

This is loosely based on some work started by @grantr [here](https://github.com/kubernetes-sigs/controller-runtime/compare/master...grantr:opencensus-replace#diff-bb94124aff8d568cb4e82854c7d44fd1)

Fixes: https://github.com/knative/pkg/issues/522
