Fix use of deprecated Ginkgo progress option

[erikgb]

While debugging some failed tests, I noticed that we use a deprecated Ginkgo option. This PR fixes it with what I think would be equivalent functionality.

Warning when running tests:

--ginkgo.progress is deprecated .  The functionality provided by --progress was confusing and is no longer needed.  Use --show-node-events instead to see node entry and exit events included in the timeline of failed and verbose specs.  Or you can run with -vv to always see all node events.  Lastly, --poll-progress-after and the PollProgressAfter decorator now provide a better mechanism for debugging specs that tend to get stuck

LGTM!
