Rule warnings are logged with numDropped=N while every other component uses num_dropped=N:
```
notifier/notifier.go: level.Warn(n.logger).Log("msg", "Alert batch larger than queue capacity, dropping alerts", "num_dropped", d)
notifier/notifier.go: level.Warn(n.logger).Log("msg", "Alert notification queue full, dropping alerts", "num_dropped", d)
storage/remote/write_handler.go: _ = level.Warn(h.logger).Log("msg", "Error on ingesting out-of-order exemplars", "num_dropped", outOfOrderExemplarErrs)
rules/group.go: level.Warn(logger).Log("msg", "Error on ingesting out-of-order result from rule evaluation", "num_dropped", numOutOfOrder)
rules/group.go: level.Warn(logger).Log("msg", "Error on ingesting too old result from rule evaluation", "num_dropped", numTooOld)
rules/group.go: level.Warn(logger).Log("msg", "Error on ingesting results from rule evaluation with different value but same timestamp", "num_dropped", numDuplicates)
scrape/scrape.go: level.Warn(sl.l).Log("msg", "Error on ingesting out-of-order samples", "num_dropped", appErrs.numOutOfOrder)
scrape/scrape.go: level.Warn(sl.l).Log("msg", "Error on ingesting samples with different value but same timestamp", "num_dropped", appErrs.numDuplicates)
scrape/scrape.go: level.Warn(sl.l).Log("msg", "Error on ingesting samples that are too old or are too far into the future", "num_dropped", appErrs.numOutOfBounds)
scrape/scrape.go: level.Warn(sl.l).Log("msg", "Error on ingesting out-of-order exemplars", "num_dropped", appErrs.numExemplarOutOfOrder)
```
Rename numDropped to num_dropped for consistency.

Using testify outside of unit tests results in panics rather than a
useful error for the user.

After #13771, the list for specific parts of the codebase looks like
it is part of the "general maintainers" list. This commit makes things
clearer.

Use `docker-repo-name` as the make target so that a repo Makfile can
override the common target implementation.

Since we skip repos that don't have a Dockerfile, we can force sync the
`.github/workflows/container_description.yml` config.

I was bored on a train and I spent some amount of time trying to scratch
some nanoseconds off the Labels.Compare when running with stringlabels.
I would be ashamed to admit the real amount of time I spent on it.
The worst thing is, I can't really explain why this is performing so
much better, and someone should re-run the benchmarks on their machine
to confirm that it's not something related to general relativity because
the train is moving. I also added some extra real-life benchmark cases
with longer labelsets (these aren't the longest we have in production,
but kubernetes labelsets are fairly common in Prometheus so I thought it
would be nice to have them).
My benchmarks show this diff:
