Remove e2e test that checked scheduler priority function for spreading of ReplicationController pods

**What this PR does / why we need it**:
Remove e2e test that checked scheduler priority function for spreading of ReplicationController pods.
The test is flaky in our test clusters, but passes in our local clusters. It looks like our e2e test clusters are not deterministic enough for checking all of the scheduler priority functions. Besides, this functionality is checked extensively by our unit tests.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #47769

**Special notes for your reviewer**:
