scheduler_perf: use ktesting.TContext + staging StartTestServer

Browse Source 
ktesting.TContext combines several different interfaces. This makes the code
simpler because less parameters need to be passed around.

An intentional side effect is that the apiextensions client interface becomes
available, which makes it possible to use CRDs. This will be needed for future
DRA tests.

Support for CRDs depends on starting the apiserver via
k8s.io/kubernetes/cmd/kube-apiserver/app/testing because only that enables the
CRD extensions. As discussed on Slack, the long-term goal is to replace the
in-tree StartTestServer with the one in staging, so this is going in the right
direction.
