Updated prometheus adapter deployment to use a multi arch image repo

Make node-exporter listening address configurable

Fix AlertmanagerConfigInconsistent alert

Update prometheus-adapter endpoint

Previously the alert would fire when the number of Alertmanager pods
didn't match the number of replicas defined in the Alertmanager spec
even though all the running pods had the same configuration hash. This
type of issue is already covered by KubeStatefulSetUpdateNotRolledOut
(and possibly KubePodNotReady), having AlertmanagerConfigInconsistent
also active in this situation creates unnecessary noise.

With this change, the alert expression only returns when Alertmanager
pods have different configuration hash values irrespective of the number
of pod replicas. The message annotation has also been enhanced to report
the configuration hash for each pod.

Update grafana dashboard docs

Instructions to add Grafana dashboard do not work. The proposed
functions are wrong, according to
[grafana.libsonnet](https://github.com/brancz/kubernetes-grafana/blob/master/grafana/grafana.libsonnet)
`dashboards` and `rawDashboards` should be used in `grafana+::`
field.

This PR updates the existing documentation and fixes minor typos.

Update kubelet config section and compatibility

This readme update includes two changes:
 1) Update the kubelet config requirements to mention the modern (non-deprecated) kubelet configuration values that can be used in place of the flags
 2) Update the compatibility matrix to mention the issue running release-0.4 on kubernetes versions 1.16.2 through 1.16.4, including a workaround.

Node exporter ignore pod mounts

update generated files for prometheus operator v0.39.0

The ignored filesystem types now matches the default, so the
comment and arg can be removed.

Ignore kubelet pod filesystem mounts of the form:
/var/lib/kubelet/pods/1b260ce7-e75d-44d4-8409-922d2bd0851f/volumes...
Metrics for these volumes are available via the kubelet_volume_stats*
metrics.
