retry GetThirdPartyGroupVersions
GetThirdPartyGroupVersions() may return a "NotFound" error if a thirdparty group is deleted in the interim between the group-discovery and the resource-discovery. This is causing e2e flakes in all tests that run kubectl, because test/e2e/thirdparty.go is creating/deleting thirdparty groups.
Fix#26425
The e2e flakes will have the following pattern:
1. the test is calling kubectl
2. error message is `Error from server: the server could not find the requested resource`
3. in the apiserver log, you should see `GET /apis/company.com/v1: (518.944µs) 404 [[kubectl/v1.3.0 (linux/amd64) kubernetes/ae28564] 104.154.110.118:46043]`

Fix panic when the namespace flag is not present
We don't set the namespace in OpenShift, so we need to check if the namespace flag is present.

Sort revisions in rollout history as integers
Previously keys were sorted as strings, thus it was possible to see such order as 1, 10, 2, 3, 4, 5.

Stabilize map order in kubectl describe
Refs #25251.
Add `SortedResourceNames()` methods to map type aliases in order to achieve stable output order for `kubectl` descriptors.
This affects QoS classes, resource limits, and resource requests.
A few remarks:
1. I couldn't find map usages for described fields other than the ones mentioned above. Then again, I failed to identify those programmatically/systematically. Pointers given, I'd be happy to cover any gaps within this PR or along additional ones.
1. It's somewhat difficult to deterministically test a function that brings reliable ordering to Go maps due to its randomizing nature. None of the possibilities I came up with (rely a "probabilistic testing" against repeatedly created maps, add complexity through additional interfaces) seemed very appealing to me, so I went with testing my `sort.Interface` implementation and the changed logic in `kubectl.describeContainers()`.
1. It's apparently not possible to implement a single function that sorts any map's keys generically in Go without producing lots of boilerplate: a `map[<key type>]interface{}` is different from any other map type and thus requires explicit iteration on the caller site to convert back and forth. Unfortunately, this makes it hard to completely avoid code/test duplication.
Please let me know what you think.

Downward API implementation for resources limits and requests
This is an implementation of Downward API for resources limits and requests, and it works with environment variables and volume plugin.
This is based on proposal https://github.com/kubernetes/kubernetes/pull/24051. This implementation follows API with magic keys approach as discussed in the proposal.
