Add the links to the changelogs of the freshly updated components to the
automated PR that does the update. This allow verifying that we are not
missing any important changes before merging the update. This happened
recently with node-exporter 1.2 which changed some flag names that we
took 3 months to update.

The current implementation of prometheus-adapter exposes a lot of
metrics about the health of its aggregated apiserver. The issue is that
the some of these metrics are not very useful in the context of
prometheus-adapter, and we currently can't avoid exposing them since
they are registered to the Kubernetes global Prometheus registry. Until
this is improved in upstream Kubernetes, we could benefit from dropping
some of the metrics that are not very useful.
Before this change, in a default kube-prometheus installation, we would
have 800+ series for prometheus-adapter against 400+, so we divided the
number of series by two will focusing on the most valuable metrics for
prometheus-adapter.

This change drops pod-centric metrics without a non-empty 'container' label.
Previously we dropped pod-centric metrics without a (pod, namespace) label set
however these can be critical for debugging.
Instead of running kubeconform on only one version of Kubernetes, it
would be better to run it against the 2 latests versions of Kubernetes
that kube-prometheus supports, so that the validation will be in line
with our support policy.

Reduce threshold of NodeFilesystemSpaceFillingUp warning alert to 20% space available, instead of 40% (default).
This will align the threshold according to default kubelet GC values
below[1],
"imageMinimumGCAge": "2m0s",
"imageGCHighThresholdPercent": 85,
"imageGCLowThresholdPercent": 80,

According to our policy, main branch of kube-prometheus should support
the 2 latest versions of Kubernetes. These changes update the tests and
the compatibility matrix to reflect that.
