Refactor leader election package test code to remove redundant code
**What this PR does / why we need it**:
leader election object supports locking on 2 objects currently endpoints and configmap. The test code for both is almost identical. This pr attempts to remove redundancy in test code for easier maintenance and extension.
**Special notes for your reviewer**:
I am trying to add leader election feature to federation controller manager and this pr is one of sub-task of the overall work documented in #44283
**Release note**:

NONE

Remove ObjectMetaFor
Builds on https://github.com/kubernetes/kubernetes/pull/43767
The second commit removes `ObjectMetaFor`. This was debt we left around after we created the interfaces. Fixing this makes it possible to start running `Unstructured` through generic storage.

bump(github.com/onsi/ginkgo):v1.2.0-94-g5ca1211
Picks up parallel execution improvements in Ginkgo that distribute jobs more evenly with parallel runs. Opened after observing long tail runs in OpenShift - testing there showed a much more compact run in terms of CPU https://github.com/onsi/ginkgo/issues/333
We'll need some soak time to be sure this has no issues.

hack/cluster: download cfssl if not present
hack/local-up-cluster.sh uses cfssl to generate certificates and
will exit it cfssl is not already installed. But other cluster-up
mechanisms (GCE) that generate certs just download cfssl if not
present. Make local-up-cluster.sh do that too so users don't have
to bother installing it from somewhere.

federation: avoid double core group registration
The federation apiserver installed its custom core group into the global `pkg/api` registry, leading to double registration. Luckily (or maybe unfortunately) we did not fail hard in this case, but the init funcs just ignored the error.
This PR creates an extra apigroup registry based on the already existing federation `core.Scheme`. This decouples the two core groups (which happen to co-exist in hyperkube).

Admission plugin to merge pod and namespace tolerations for restricting pod placement on nodes
```release-note
This admission plugin checks for tolerations on the pod being admitted and its namespace, and verifies if there is any conflict. If there is no conflict, then it merges the pod's namespace tolerations with the the pod's tolerations and it verifies them against its namespace' whitelist of tolerations and returns. If a namespace does not have its default or whitelist tolerations specified, then cluster level default and whitelist is used. An example of its versioned config:
apiVersion: apiserver.k8s.io/v1alpha1
kind: AdmissionConfiguration
plugins:
- name: "PodTolerationRestriction"
configuration:
apiVersion: podtolerationrestriction.admission.k8s.io/v1alpha1
kind: Configuration
default:
- Key: key1
Value: value1
- Key: key2
Value: value2
whitelist:
- Key: key1
Value: value1
- Key: key2
Value: value2

remove go-restful from namer for rest handling
Our RESTHandler code is currently tightly coupled to go-restful, but there's no reason for this coupling. It makes integrations that want API handling (decode, sanity check, admission, verb handling), but don't need the REST installer flow impractical. I know of two layers now: metrics and TPR.
This starts the process of unwinding by switching the `ScopeNamer` (used for request identification and selflinks) to use the standard http library along with the `RequestInfo` we place in the context for authorization and any other interested layer.

only log stacks on server errors
Stack traces on http logging statements can be useful, but you usually only need them for server errors not for things like redirects or even client errors since the server won't be fixing those.
This tightens the "log stack" behavior to only happen for server errors. Messages will still be logged, but the automatic stacks will only come out for server errors.

@jsafrane, as many of our users are confused by the original message, can we fix the message first and then consider how to control the count of the events?
