* manually install kind

* add alias to kind

* use full kind name

* one more name change

* install kind with other tools

* add bind mounts instead of copying files

* test fetching the runner image

* bump up go version

* install pinned version of kind before any test run

* do not overwrite local ./manifests during test run

* update the docs

* fix kind name

* update go.* files

* fix deps

* avoid unnecessary image upload

The operator provides reference end-to-end (e2e) tests to
ensure various infrastructure parts work smoothly together. The test code is available at `e2e/tests`.
The special `registry.opensource.zalan.do/acid/postgres-operator-e2e-tests-runner` image is used to run the tests. The container mounts the local `e2e/tests` directory at runtime, so whatever you modify in your local copy of the tests will be executed by a test runner. By maintaining a separate test runner image we avoid the need to re-build the e2e test image on every build.
Each e2e execution tests a Postgres Operator image built from the current git branch. The test
runner creates a new local K8s cluster using [kind](https://kind.sigs.k8s.io/),
utilizes provided manifest examples, and runs e2e tests contained in the `tests`
folder. The K8s API client in the container connects to the `kind` cluster via
