Batch etcdlog intervals to prevent hundreds of thousands slamming browser charts

[dgoodwin]

Runs like https://prow.ci.openshift.org/view/gs/test-platform-results/logs/periodic-ci-openshift-release-master-nightly-4.22-e2e-rosa-sts-ovn/2018612074661285888 have 200k etcdlog intervals. Turns out etcd can log the messages we watch for a LOT. These intervals are in memory on any prow job page load, and make interval charts brutally slow to load if they do at all.

This change batches them on minute boundaries, we'll see the message, the locator, and a count within that minute, but it cuts hundreds of thousands of intervals down to less than 400 in this case.
