`--namespace` is a very common flag for nearly every `kubectl` command we have. We should claim `-n` for it.

Node controller deletePod return true if there are pods pending deletion
Fixes https://github.com/kubernetes/kubernetes/issues/30536
If a node had a single pod in terminating state, and that node no longer reported healthy, the pod was never deleted by the node controller because it believed there were no pods remaining.

add --raw for kubectl get
Adds a `--raw` option to `kubectl get` that allow you specify your URI, but use the transport built by `kubectl`. This is especially useful when working with secured environments that require authentication and authorization to hit non-api endpoints. For example, `kubect get --raw /metrics` or if you want to debug a watch with a view at the exact data `kubectl get --raw '/api/v1/namespaces/one/replicationcontrollers?watch=true'`.

Support for preexisting replicas and estimated capacity in federated replicaset controller
With this PR the planer will be able to:
* Keep already existing replicas in their current clusters if rebalance = false and min/max boundaries are met.
* Limit the number of replicas in a cluster to the level that was measured by the count of running and unschedulable pods. And provide an estimate how much more pods would be nice to put in a cluster so that if they are scheduled we will be closer to the desired layout or to schedule the desired number of replicas at all.

Add Events for operation_executor to show status of mounts, failed/successful to show in describe events
Fixes#27590
@saad-ali @pmorie @erinboyd
After talking with @pmorie last week about the above issue, I decided to poke around and see if I could remedy. The refactoring broke my previous UXP merged PR's that correctly showed failed mount errors in the describe events. However, Not sure I implemented correctly, but it tested out and seems to be working, let me know what I missed or if this is not the correct approach.

Resolution hint: Check and make sure the NFS Server exists (ensure that correct IPAddress/Hostname was given) and is available/reachable.
Also make sure firewall ports are open on both client and NFS Server (2049 v4 and 2049, 20048 and 111 for v3).
Use commands telnet <nfs server> <port> and showmount <nfs server> to help test connectivity.

Federated replica set pod analyser
A helper function that analyses a list of pods and checks how many of them (per cluster) are running or are unschedulable.
This function should be replaced by a smarter/more effective informer that would count these values on the fly. Unfortunately this needs the ownerRef feature which may not be ready/enabled in 1.4.
WIP because tests are not there yet. Will be added in the evening (PL time).

OpenAPI / Swagger2 spec generation
This is alpha version of OpenAPI spec generation. Generated "/swagger.json" file (accessible on api server) is a valid OpenAPI spec with some warnings that will be fixed in next versions of spec generation. Currently it is possible to generate a client using this spec though I did not test the clients.
reference: #13414
**Release note**:
```release-note
Alpha support for OpenAPI (aka. Swagger 2.0) specification serves on /swagger.json
```
