* 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.

* CNI: Use skip ports configuration in CNI
This PR updates the install and `cmdAdd` workflow (which is called
for each new Pod creation) to retrieve and set the configured Skip
Ports. This also updates the `cmdAdd` workflow to check if the new
pod is a control plane Pod, and adds `443` to OutBoundSkipPort so
that 443 (used with k8s API) is skipped as it was causing errors because
a resolve lookup was happening for them which is not intended.
* 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.

As part of the effort to remove the "experimental" label from the CNI plugin, this PR introduces cni checks to `linkerd check`

The new proxy has changed its configuration as follows:
- `LISTENER` urls are now `LISTEN_ADDR` addresses;
- `CONTROL_URL` is now `DESTINATION_SVC_ADDR`;
- `*_NAMESPACE` vars are no longer needed;
- The `PROXY_ID` is now the `DESTINATION_CONTEXT`;
- The "metrics" port is now the "admin" port, since it serves more than
just metrics;
- A readiness probe now checks a dedicated /ready endpoint eagerly.
Identity injection is **NOT** configured by this branch.
When changing templates, it's can be pretty time-intensive to
repair all test fixtures.
This change instruments CLI tests with two flags, `-update` and
`-pretty-diff` that control how test fixtures are diffed. When the
`-update` flag is set, the tests fixtures are overwritten as tests
execute. The `-pretty-diff` flag causes the full text of the fixture
to be printed on mismatch.
* Export RootOptions and BuildFirewallConfiguration so that the cni-plugin can use them.
* Created the cni-plugin based on istio-cni implementation
* Create skeleton files that need to be filled out.
* Create the install scripts and finish up plugin to write iptables
* Added in an integration test around the install_cni.sh and updated the script to handle the case where it isn't the only plugin. Removed the istio kubernetes.go file in favor of pkg/k8s; initial usage of this package; found and fixed the typo in the ClusterRole and ClusterRoleBinding; found the docker-build-cni-plugin script
* Corrected an incorrect name in the docker build file for cni-plugin
* Rename linkerd2-cni to linkerd-cni
* Fixup Dockerfile and clean up code a bit as well as logging statements.
* Update Gopkg.lock after master merge.
* Update test file to remove temporary tag.
* Fixed the command to run during the test while building up the docker run.
* Added attributions to applicable files; in the test file, use a different container for each test scenario and also print the docker logs to stdout when there is an error;
* Add the --no-init-container flag to install and inject. This flag will not output the initContainer and will add an annotation assuming that the cni will be used in this case.
* Update .travis.yml to build the cni-plugin docker image before running the tests.
* Workaround golint warnings.
* Create a new command to install the linkerd-cni plugin.
* Add the --no-init-container option to linkerd inject
* Use the setup ip tables annotation during the proxy auto inject webhook prevent/allow addition of an init container; move cni-plugin tests to the integration-test section of travis
* gate the cni-plugin tests with the -integration-tests flag; remove unnecessary deployment .yaml file.
* Incorporate PR Cleanup suggestions.
* Remove the SetupIPTablesLabel annotation and use config flags and the presence of the init container to determine whether the cni-plugin writes ip tables.
* Fix a logic bug in the cni-plugin code that prevented the iptables from being written; Address PR comments; make tests pass.
* Update go deps shas
* Changed the single file install-cni plugin filename to be .conf vs .conflist; Incorporated latest PR comments around spacing with the new renderer among others.
* Fix an issue with renaming .conf to .conflist when needed.
* Renamed some of the variables to try to make it more clear what is going on.
* Address final PR comments.
* Hide cni flags for the time being.
