Add support for k8s 1.16 (#3364)
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.

Alejandro Pedraza bd1955c317 When injecting, perform an uninject as a first step (#2089)
* When injecting, perform an uninject as a first step

Fixes #1970

The fixture `inject_emojivoto_already_injected.input.yml` is no longer
rejected, so I created the corresponding golden file.

Note that we'll still forbid injection over resources already injected
with third party meshes (Istio, Contour), so now we have
`HasExisting3rdPartySidecars()` to detect that.

* Generalize HasExistingSidecars() to cater for both the auto-injector and
* Convert `linkerd uninject` result format to the one used in `linkerd inject`.
* More updates to the uninject reports. Revert changes to the HasExistingSidecars func.

Introduce inject check for known sidecars (#1619)
`linkerd inject` was not checking its input for known sidecars and
initContainers.

Modify `linkerd inject` to check for existing sidecars and
initContainers, specifically, Linkerd, Istio, and Contour.

Part of #1516
