clarify failure message

The failure message for "[sig-cluster-lifecycle] cluster upgrade should be fast" is ambiguous:

upgrade to registry.build01.ci.openshift.org/ci-op-h21l7wld/release@sha256:2148b1c121946ac4f186bb22b166247d3df0ad9cf3966f05dc2a6ea27bc53927 took too long: 86.33481681223333

What does 86.33481681223333 represent? Is it seconds, minutes, hours? What does "too long" mean? Without looking at the test code, one cannot tell. With that info added to the failure string, it's easier to understand:

upgrade to registry.build01.ci.openshift.org/ci-op-h21l7wld/release@sha256:2148b1c121946ac4f186bb22b166247d3df0ad9cf3966f05dc2a6ea27bc53927 took too long: 86.3 minutes, expected 75 minutes or less
