beorn7 0e3f35324b scrape: Enable ingestion of multiple exemplars per sample
This has become a requirement for native histograms, as a single
histogram sample commonly has many buckets, so that providing many
exemplars makes sense.

Since OM text doesn't support native histograms yet, the test had to
be expanded to also support protobuf test cases.
