[Federation] Fix flake in TestUpdateClusterRace
**What this PR does / why we need it**:
Fix#50262
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#50262
**Special notes for your reviewer**:
Although we do locking/unlocking while using protected data in ClusterController, there are chances that `clusterClient` can be deleted as it is a pointer. Also its better to lock/unlock once for the function `UpdateClusterStatus` instead of multiple locks/unlocks.
**Release note**:
```
NONE

[Federation] Make the hpa scale time window configurable
This PR is on top of open pr https://github.com/kubernetes/kubernetes/pull/45993.
Please review only the last commit in this PR.
This adds a config param to controller manager, the value of which gets passed to hpa adapter via sync controller.
This is needed to reduce the overall time limit of the hpa scaling window to much lesser (then the default 2 mins) to get e2e tests run faster. Please see the comment on the newly added parameter.
**Special notes for your reviewer**:
@kubernetes/sig-federation-pr-reviews
@quinton-hoole
@marun to please validate the mechanism used to pass a parameter from cmd line to adapter.
**Release note**:
```
federation-controller-manager gets a new flag --hpa-scale-forbidden-window.
This flag is used to configure the duration used by federation hpa controller to determine if it can move max and/or min replicas
around (or not), of a cluster local hpa object, by comparing current time with the last scaled time of that cluster local hpa.
Lower value will result in faster response to scalibility conditions achieved by cluster local hpas on local replicas, but too low
a value can result in thrashing. Higher values will result in slower response to scalibility conditions on local replicas.

[Federation] HPA controller
This PR implements the design listed in https://github.com/kubernetes/community/pull/593.
This is still a work in progress, and needs more unit tests to be added.
I will add the integration tests and e2e tests in a separate PR(s).
@kubernetes/sig-federation-pr-reviews
**Release note**:
```
Horizontal Pod Autoscaling is now available as an alpha feature in federation.
It can be used to distribute and scale workload across clusters joined in a federation.
In its current form, it works only on cpu utilization and the support for other metrics is yet to be built in.

updates for ClusterController's maps were made without locking which can lead
to race conditions which were detectede in https://github.com/kubernetes/kubernetes/issues/49958
This change adds a RWMutex to protect the data. We lock and unlock them
whenever the data is accessed to make sure that we dont slow down too much.

Federation: Add delaying deliverer to dns controller
**What this PR does / why we need it**:
- if `ensureDNSRecords` returned an error there was no retry, so now introduced an delaying deliverer which would reattempt to do ensureDNSRecords.
- ~~Revamped unit test cases of DNS controller. Added more test cases and increased the test coverage.
This was a leftover job from earlier refactoring PR's.~~

Adding option to set the federation api server port if nodeport is set
**What this PR does / why we need it**: Kubefed will deploy the respected services and then it will do a health check. Prior to this patch if the user selects the nodeport a random port is opened. In environments where firewalls are in place this random port selection will cause the health check to fail. With this patch we enable users to designate a specific port, after for example opening it on their firewall.

Return clusterErr rather than err
The updateClusterIngressUIDToMasters() should return clusterErr, not err.
If the 'err' of 'masterCluster, masterUID, err := ic.getMasterCluster()' is nil and the 'clusterErr' of 'clusterObj, clusterErr := api.Scheme.DeepCopy(cluster)' is not nil, updateClusterIngressUIDToMasters() will return ("", nil).
And do not log fallbackUID when fallbackUID is nil.
