Add two pd tests with default grace period
Add two tests in pd.go. They are same as the flaky test, but the pod deletion has default grace period

Kubelet should mark VolumeInUse before checking if it is Attached
Kubelet should mark VolumeInUse before checking if it is Attached.
Controller should fetch fresh copy of node object before detach instead of relying on node informer cache.
Fixes#27836
Ensure that kublet marks VolumeInUse before checking if it is Attached.
Also ensures that the attach/detach controller always fetches a fresh
copy of the node object before detach (instead ofKubelet relying on node
informer cache).

Refactored, expanded and fixed federated-services e2e tests.
1. Moved BeforeEach() and AfterEach() to an inner scope, to prevent clashes with Framework's BeforeEach() and AfterEach(). Morte to come on this, as it's a major bug in our use of Ginkgo, and affects many other tests.
2. Keep track of which clusters we have created namespaces in, so that we don't try to delete namespaces out of clusters that we didn't create them in (e.g. the primary cluster, where the framework already creates and deleted the required namespace).
3. Separate tests for federated service creation and verification that underlying services are created correctly.
4. For DNS resolution tests, create backend pods (and delete on cleanup) where required).
5. For non-local DNS resolution, delete a backend pod in one cluster to test, and in the remainder of clusters on cleanup.
6. Lots of refactoring to make code re-usable across multiple test.
7. Lots of debugging/fixing to make sure that everything that the testscreate are cleaned up properly afterwards, and don't clash with the cleanups done by the e2e Framework.

TLS bootstrap API group (alpha)
This PR only covers the new types and related client/storage code- the vast majority of the line count is codegen. The implementation differs slightly from the current proposal document based on discussions in design thread (#20439). The controller logic and kubelet support mentioned in the proposal are forthcoming in separate requests.
I submit that #18762 ("Creating a new API group is really hard") is, if anything, understating it. I've tried to structure the commits to illustrate the process.

Dedent
Adding the dedent package and then applying it to the kubectl help commands. Also updating the documentation to reflect the use of dedent.
Using new fake clientset registry exposes the actual flow on pending
namespace finalization: get namespace, create finalizer, list pods and
delete namespace if there are no pods.
Since fake clientset now correctly tracks objects created by deployment
controller, it triggers different controller behavior: controller only
creates replica set once and updates deployment once.
Fake clientset no longer needs to be prepopulated with records: keeping
them in leads to the name conflict on creates. Also, since fake
clientset now respects namespaces, we need to correctly populate them.

refactor quota evaluation to cleanly abstract the quota access
This refactor cleanly separates out the quota accessor parts of the evaluator. This change made it easier to shutdown nicely and pulls the object retrieval logic (which has become rather complex in and of itself) out of the main evaluation flow.
@derekwaynecarr
Fake clientset is used by unit tests extensively but it has some
shortcomings:
- no filtering on namespace and name: tests that want to test objects in
multiple namespaces end up getting all objects from this clientset,
as it doesn't perform any filtering based on name and namespace;
- updates and deletes don't modify the clientset state, so some tests
can get unexpected results if they modify/delete objects using the
clientset;
- it's possible to insert multiple objects with the same
kind/name/namespace, this leads to confusing behavior, as retrieval is
based on the insertion order, but anchors on the last added object as
long as no more objects are added.
This change changes core.ObjectRetriever implementation to track object
adds, updates and deletes.
Some unit tests were depending on the previous (and somewhat incorrect)
behavior. These are fixed in the following few commits.

vSphere provider - Adding config for working dir
This allows the user the set "working-dir" in their vsphere.cfg file.
The value should be a path in the vSphere datastore in which the
provider will look for vms. This should help compartmentalize
workloads in vSphere.
