*From the comment disabling the test*:
#2316
The response from `http://httpbin.org/get` is non-deterministic--returning
either `http://..` or `https://..` for GET requests. As #2316 mentions, this
test should not have an external dependency on this endpoint. As a workaround
for edge-20.1.3, temporarily disable this test and renable with one that has
reliable behavior.

## edge-20.1.3
* CLI
* Introduced `linkerd check --pre --linkerd-cni-enabled`, used when the CNI
plugin is used, to check it has been properly installed before proceeding
with the control plane installation
* Added support for the `--as-group` flag so that users can impersonate
groups for Kubernetes operations (thanks @mayankshah160!)
* Controller
* Fixed an issue where an override of the Docker registry was not being
applied to debug containers (thanks @javaducky!)
* Added check for the Subject Alternate Name attributes to the API server
when access restrictions have been enabled (thanks @javaducky!)
* Added support for arbitrary pod labels so that users can leverage the
Linkerd provided Prometheus instance to scrape for their own labels
(thanks @daxmc99!)
* Fixed an issue with CNI config parsing

In various integration tests we're not showing stderr when a failure
happens, thus hiding some possibly useful debugging info.
E.g. in the latest CI failures, commands like `linkerd update` were
failing with no visible reason why.
Fixes#3356
1.16 removes some api groups that were already deprecated. From k8s blog
post (https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/):
```
- PodSecurityPolicy: will no longer be served from extensions/v1beta1 in
v1.16.
Migrate to the policy/v1beta1 API, available since v1.10. Existing
persisted data can be retrieved/updated via the policy/v1beta1 API.
- DaemonSet, Deployment, StatefulSet, and ReplicaSet: will no longer be
served from extensions/v1beta1, apps/v1beta1, or apps/v1beta2 in v1.16.
Migrate to the apps/v1 API, available since v1.9. Existing persisted
data can be retrieved/updated via the apps/v1 API.
```
Previous PRs had already made this change at the Helm templates level,
but we still needed to do it at the API calls and tests.
The integration tests ran fine for k8s 1.12 and 1.15. They fail on 1.16
because the upgrade integration test tries to install linkerd 2.5 which is not
compatible with 1.16.

Integration tests may fail and leave behind namespaces that following
builds aren't able to clean up because the git sha is being included in
the namespace name, and the following builds don't know about those
shas.
This modifies the `test-cleanup` script to delete based on object labels
instead of relying on the objects names, now that after 2.4 all the
control plane components are labeled. Note that this will also remove
non-testing linkerd namespaces, but we were already kinda doing that
partially because we were removing the cluster-level resources (CRDs,
webhook configs, clusterroles, clusterrolebindings, psp).
`test-cleanup` no longer receives a namespace name as an argument.
The data plane namespaces aren't labeled though, so I've added the
`linkerd.io/is-test-data-plane` label for them in
`CreateNamespaceIfNotExists()`, and making sure all tests that need a
data plaine explicitly call that method instead of creating the
namespace as a side-effect in `KubectlApply()`.

This change introduces integration tests for `linkerd inject`. The tests
perform CLI injection, with and without params, and validates the
output, including annotations.
Also add some known errors in logs to `install_test.go`.

The httpbin responses recently started returning `url` fields starting
with `https`, regardless of the protocol used in the request.
This change modifies the egress integration test to always expect
`https` in the `url` response field.
This is a workaround until #2316 is implemented.

When running integration tests in a Kubernetes cluster that sometimes takes a little longer to get pods ready, the integration tests fail tests too early because most tests have a retry timeout of 30 seconds.
This PR bumps up this retry timeout for `TestInstall` to 3 minutes. This gives the test enough time to download any new docker images that it needs to complete succesfully and also reduces the need to have large timeout values for subsequent tests. This PR also refactors `CheckPods` to check that all containers in a pods for a deployment are in a`Ready` state. This helps also helps in ensuring that all docker images have been downloaded and the pods are in a good state.
Tests were run on the community cluster and all were successful.

If an input file is un-injectable, existing inject behavior is to simply
output a copy of the input.
Introduce a report, printed to stderr, that communicates the end state
of the inject command. Currently this includes checking for hostNetwork
and unsupported resources.
Malformed YAML documents will continue to cause no YAML output, and return
error code 1.
This change also modifies integration tests to handle stdout and stderr separately.
example outputs...
some pods injected, none with host networking:
```
hostNetwork: pods do not use host networking...............................[ok]
supported: at least one resource injected..................................[ok]
Summary: 4 of 8 YAML document(s) injected

This PR begins to migrate Conduit to Linkerd2:
* The proxy has been completely removed from this repo, and is now located at
github.com/linkerd/linkerd2-proxy.
* A `Dockerfile-proxy` has been added to fetch the most-recently published proxy
binary from build.l5d.io.
* Proxy-specific protobuf bindings have been moved to
github.com/linkerd/linkerd2-proxy-api.
* All docker images now use the gcr.io/linkerd-io registry.
* `inject` now uses `LINKERD2_PROXY_` environment variables
* Go paths have been updated to reflect the new (future) repo location.
* Add tests/utils/scripts for running integration tests
Add a suite of integration tests in the `test/` directory, as well as
utilities for testing in the `testutil/` directory.
You can use the `bin/test-run` script to run the full suite of tests,
and the `bin/test-cleanup` script to cleanup after the tests.
The test/README.md file has more information about running tests.
@pcalcado, @franziskagoltz, and @rmars also contributed to this change.
* Create TEST.md file at the root of the repo
* Update based on review feedback
* Relax external service IP timeout for GKE
* Update TEST.md with more info about different types of test runs
* More updates to TEST.md based on review feedback
