Add in cluster check after benchmark runs

[paigerube14]

Want to add in an extra check after the certain benchmarks are run to verify the cluster is in a decent state

Many of the runs I've seen recently, the benchmark finishes but some of the nodes go notready. In this case I feel we should fail the test but currently it is passing

My thoughts here are running 1 iteration of cerberus to be able to check a multitude of different components of Openshift. Need to add into each of the scale-ci to call at the end of the benchmark

Passing run here: ...scale-ci/job/paige-e2e-multibranch/job/cerberus/25/
