The new proxy has changed its configuration as follows:
- `LISTENER` urls are now `LISTEN_ADDR` addresses;
- `CONTROL_URL` is now `DESTINATION_SVC_ADDR`;
- `*_NAMESPACE` vars are no longer needed;
- The `PROXY_ID` is now the `DESTINATION_CONTEXT`;
- The "metrics" port is now the "admin" port, since it serves more than
just metrics;
- A readiness probe now checks a dedicated /ready endpoint eagerly.
Identity injection is **NOT** configured by this branch.
- Created the pkg/inject package to hold the new injection shared lib.
- Extracted from `/cli/cmd/inject.go` and `/cli/cmd/inject_util.go`
the core methods doing the workload parsing and injection, and moved them into
`/pkg/inject/inject.go`. The CLI files should now deal only with
strictly CLI concerns, and applying the json patch returned by the new
lib.
- Proceeded analogously with `/cli/cmd/uninject.go` and
`/pkg/inject/uninject.go`.
- The `InjectReport` struct and helping methods were moved into
`/pkg/inject/report.go`
- Refactored webhook to use the new injection lib
- Removed linkerd-proxy-injector-sidecar-config ConfigMap
- Added the ability to add pod labels and annotations without having to
specify the already existing ones

* 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.
