v1.22.0

This release includes an extension of our current metrics to also include the internals of k8s.io/cloud-provider with respect to the work queue depth and requests to the Kubernetes API.

Besides having all data available, this will also help us with debugging #661.

Features

• metrics: add metrics from cloud-provider library (#824)
• load-balancer: emit warning if unsupported port protocol is configured (#828)
• allow arbitrary length API tokens (#752)
