Bryan Boreham 8065bef172 Move metric type definitions to common/model
They are used in multiple repos, so common is a better place for them.
Several packages now don't depend on `model/textparse`, e.g.
`storage/remote`.

Also remove `metadata` struct from `api.go`, since it was identical to
a struct in the `metadata` package.

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.

beorn7 9e500345f3 textparse/scrape: Add option to scrape both classic and native histograms
So far, if a target exposes a histogram with both classic and native
buckets, a native-histogram enabled Prometheus would ignore the
classic buckets. With the new scrape config option
`scrape_classic_histograms` set, both buckets will be ingested,
creating all the series of a classic histogram in parallel to the
native histogram series. For example, a histogram `foo` would create a
native histogram series `foo` and classic series called `foo_sum`,
`foo_count`, and `foo_bucket`.

This feature can be used in a migration strategy from classic to
native histograms, where it is desired to have a transition period
during which both native and classic histograms are present.

Note that two bugs in classic histogram parsing were found and fixed
as a byproduct of testing the new feature:

1. Series created from classic _gauge_ histograms didn't get the
   _sum/_count/_bucket prefix set.
2. Values of classic _float_ histograms weren't parsed properly.
