* viz: add render golden tests
This branch adds golden tests for the viz install. This would be
useful to track changes in render as more changes are added.
This also moves the common code that is used across extensions
to generate diffs into `testutil` to be able to be used widely.

Fixes#4874
This branch upgrades Helm sdk from v2 to v3 *without any functionaly
changes*, just replacing types with newer API's.
This should not effect our current support for Helm v2 as we did not
change any of the underlying tempaltes(which work with Helm v2). This
works becuase we did not use any of the API's that read the Chart
metadata (which are the only ones changed from v2 to v3) and currently
manually load files and pass ito the sdk.
This PR should provide a great point to start more of the newer Helm v3
API's including for the upgrade workflow thus allowing us to make
Linkerd CLI more simpler.

* Push docker images to ghcr.io instead of gcr.io
The `cloud_integration.yml` and `release.yml` workflows were modified to
log into ghcr.io, and remove the `Configure gcloud` step which is no
longer necessary.
Note that besides the changes to cloud_integration.yml and release.yml, there was a change to the upgrade-stable integration test so that we do linkerd upgrade --addon-overwrite to reset the addons settings because in stable-2.8.1 the Grafana image was pegged to gcr.io/linkerd-io/grafana in linkerd-config-addons. This will need to be mentioned in the 2.9 upgrade notes.
Also the egress integration test has a debug container that now is pegged to the edge-20.9.2 tag.
Besides that, the other changes are just a global search and replace (s/gcr.io\/linkerd-io/ghcr.io\/linkerd/).
* CNI add support for priorityClassName
As requested in #2981 one should be able to optionally define a priorityClassName for the linkerd2 pods.
With this commit support for priorityClassName is added to the CNI plugin helm chart as well as to the
cli command for installing the CNI plugin.
Also added an `installNamespace` Helm option for the CNI installation.
Implements part of #2981.
