[8.x] Remove call to super.cleanupCluster in cleanup methods which does not override parent method (elastic#122209) (elastic#122258)

* Remove call to super.cleanupCluster in cleanup methods which does not override parent method (elastic#122209)

ReindexDataStreamIndexAction.cleanupCluster called EsIntegTestCase.cleanupCluster, but did not override it. This caused EsIntegTestCase.cleanupCluster to be called twice, once in ReindexDataStreamIndexAction.cleanupCluster and once when the After annotation is called on EsIntegTestCase.

(cherry picked from commit 89ba03e)

# Conflicts:
#	muted-tests.yml

* deletePipeline not available in 8.x
