From API call WithRange and WithPrefix work the same, they just set the range end.
The difference is when the range end is provided:
* WithRange(end) requires providing the end while calling
* WithPrefix() calculates the end based on key provided to the Get.
For example, those are equal:
* client.Get(ctx, "/pods/", WithPrefix())
* client.Get(ctx, "/pods/", WithRange(GetPrfixRangeEnd("/pods/")))
As keyPrefix is equal preparedKey there should not be a difference.
There were four issues in OpenAPI aggregation cleanup:
1. When removing an APIService, openAPIAggregationController was called
twice while openAPIV3AggregationController was never called, leading
to OpenAPI v3 for the APIService not cleaned up.
2. When removing a local APIService, v2 specAggregator should not return
ErrAPIServiceNotFound when it doesn't find the APIService because
local APIServices were never added to its cache, otherwise confusing
error logs would be generated. Besides, the method's comment
indicates that the desired behavior is that no error is returned if
the APIService does not exist.
3. When removing an APIService, v3 specProxier should update
openapiv2converter's cache, like when updating an APIService,
otherwise the API would not be removed from "/openapi/v3".
4. When v3 AggregationController reconciles an APIService, it should
stop requeueing it if it fails with ErrAPIServiceNotFound as the
APIService has been removed, like what v2 AggregationController does,
otherwise it would keep reconciling the APIService forever.

When defining a ClusterIP Service, we can specify externalIP, and the
traffic policy of externalIP is subject to externalTrafficPolicy.
However, the policy can't be set when type is not NodePort or
LoadBalancer, and will default to Cluster when kube-proxy processes the
Service.
This commit updates the defaulting and validation of Service to allow
specifying ExternalTrafficPolicy for ClusterIP Services with
ExternalIPs.

returnRV was was equal to withRev, but updated at different time.
When preparing the request they are set equal to each other.
The only difference was during the for loop.
returnRV was always set no matter if pagination was enabled, while withRev only when paginating.
7a63997c8a added a global variable which gets set multiple times by
different goroutines in integration tests, leading to a data race:

Mutex locking avoids the data race. Whether this variable really can be used
safely by those concurrent (?) tests is a different question...
// AnnotateInitialEventsEndBookmark adds a special annotation to the given object
// which indicates that the initial events have been sent.
//
// Note that this function assumes that the obj's annotation
// field is a reference type (i.e. a map).
