As described in #5105, it's not currently possible to set the proxy log
level to `off`. The proxy injector's template does not quote the log
level value, and so the `off` value is handled as `false`. Thanks, YAML.
This change updates the proxy template to use helm's `quote` function
throughout, replacing manually quoted values and fixing the quoting for
the log level value.
We also remove the default logFormat value, as the default is specified
in values.yaml.
The proxy has a default, hardcoded set of ports on which it doesn't do
protocol detection (25, 587, 3306 -- all of which are server-first
protocols). In a recent change, this default set was removed from
the outbound proxy, since there was no way to configure it to anything
other than the default set. I had thought that there was a default set
applied to proxy-init, but this appears to not be the case.
This change adds these ports to the default Helm values to restore the
prior behavior.
I have also elected to include 443 in this set, as it is generally our
recommendation to avoid proxying HTTPS traffic, since the proxy provides
very little value on these connections today.
Additionally, the memcached port 11211 is skipped by default, as clients
do not issue any sort of preamble that is immediately detectable.
These defaults may change in the future, but seem like good choices for
the 2.9 release.
Most invocations of `TestHelper.LinkerdRun` don't actually need the stderr
output except to encode it in the error message. This changes this helper
to return an error that includes the full invoked command and error message.
Invocations that need direct access to stderr must call `TestHelper.PipeToLinkerdRun`
The purpose of this test is to validate that the auto injector configures the proxy and the additional containers according to the specified config.
This is done by providing a helper that can generate the desired annotations and later inspect an injected pod in order to determine that every bit of configuration has been accounted for. This test is to provide further assurance that #5036 did not introduce any regressions.

Fixes#4191#4993
This bumps Kubernetes client-go to the latest v0.19.2 (We had to switch directly to 1.19 because of this issue). Bumping to v0.19.2 required upgrading to smi-sdk-go v0.4.1. This also depends on linkerd/stern#5
This consists of the following changes:
- Fix ./bin/update-codegen.sh by adding the template path to the gen commands, as it is needed after we moved to GOMOD.
- Bump all k8s related dependencies to v0.19.2
- Generate CRD types, client code using the latest k8s.io/code-generator
- Use context.Context as the first argument, in all code paths that touch the k8s client-go interface

* tests: Add new CNI deep integration tests
Fixes#3944
This PR adds a new test, called cni-calico-deep which installs the Linkerd CNI
plugin on top of a cluster with Calico and performs the current integration tests on top, thus
validating various Linkerd features when CNI is enabled. For Calico
to work, special config is required for kind which is at `cni-calico.yaml`
This is different from the CNI integration tests that we run in
cloud integration which performs the CNI level integration tests.

* 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/).
This creates a new integration test target that launches the deep suite,
using a linkerd instance installed through Helm.
I've added a `global.proxyInit.ignoreInboundPorts=1234,5678` override
during install and enhanced the injection test to catch problems like
what we saw in #4679.
Using following command the wrong spelling were found and later on
fixed:

This PR adds a new cli test to see if installation yamls are correctly
generated even on windows, this is important because of all the file
path difference between windows and Linux, and if any code uses a wrong
format might cause the chart generation commands to fail on windows.
This creates a separate workflow for both release and integration.
Also, all the exisiting integration tests are moved in to
/tests/integration to separate from /test/cli as this test does not fall
under integration tests category
