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.

* Add control plane and CNI PSP and RBAC resources
* Add the '--linkerd-cni-enabled' flag to the multi-stage install subcommands
This flag ensures that the NET_ADMIN capability is omitted from the control
plane's PSP during 'install config' and the proxy-init containers aren't
injected during 'install control-plane'.

* 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.
