[Federation] Add integration test for secrets

This PR adds an integration test for secrets that:

 - performs create/read/update/delete on federation resources and validates that the changes are propagated to member clusters.  
 - uses an abstraction layer (fixture and adapter) to minimize the code required to support each federated type
   - It should be possible to replace a test-specific adapter with a runtime adapter in the future (as per #41050)
 - reuses fixture (federation api and clusters) across different resource types to minimize setup overhead
   - on a fast machine, setup takes ~4s, and validating each type takes ~2s  
 - uses the [Subtest feature added in Go 1.7](https://blog.golang.org/subtests) to allow the test for a specific controller to be run in isolation
   - ``make test-integration WHAT="federation  -test.run=TestFederationCRUD/secret"``

Once this PR merges the test can be extended to target other federated types.

This PR targets #40705

Cluster Federation

Kubernetes Cluster Federation enables users to federate multiple Kubernetes clusters. Please see the user guide and the admin guide for more details about setting up and using the Cluster Federation.

Building Kubernetes Cluster Federation

Please see the Kubernetes Development Guide for initial setup. Once you have the development environment setup as explained in that guide, you also need to install jq

Building cluster federation artifacts should be as simple as running:

make build

You can specify the docker registry to tag the image using the KUBE_REGISTRY environment variable. Please make sure that you use the same value in all the subsequent commands.

To push the built docker images to the registry, run:

make push

To initialize the deployment run:

(This pulls the installer images)

make init

To deploy the clusters and install the federation components, edit the ${KUBE_ROOT}/_output/federation/config.json file to describe your clusters and run:

make deploy

To turn down the federation components and tear down the clusters run:

make destroy

Ideas for improvement

  1. Continue with destroy phase even in the face of errors.

    The bash script sets set -e errexit which causes the script to exit at the very first error. This should be the default mode for deploying components but not for destroying/cleanup.
