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()`.

Support for resources opting out of tap
Implements the `linkerd inject --disable-tap` flag (although hidden pending #2811) and the config override annotation `config.linkerd.io/disable-tap`.

This changes the default behavior of `linkerd inject` to not inject the
proxy but just the `linkerd.io/inject: enabled` annotation for the
auto-injector to pick it up (regardless of any namespace annotation).
A new `--manual` mode was added, which behaves as before, injecting
the proxy in the command output.
The unit tests are running with `--manual` to avoid any changes in the
fixtures.

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`.

auto-injected cluster

Out of all the integration tests (egress, get, stat, tap and
install_test) only in stat and tap do meshed (proxy-to-proxy) connections take
place, which we can test are 100% TLS.
For stat, #2537 already added such check for connections with the
Prometheus pod (connections to other pods are not meshed, apparently).
This commit adds such check for tap.
Fixes#2519
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...

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.
