c58e20ad0e histogram: Identify native histograms even without observations 
Native histograms without observations and with a zero threshold of
zero look the same as classic histograms in the protobuf exposition
format. According to
https://github.com/prometheus/client_golang/issues/1127 , the idea is
to add a no-op span to those histograms to mark them as native
histograms. This commit enables Prometheus to detect that no-op span
and adds a doc comment to the proto spec describing the behavior.

531567d46e Drop metric name for "atan2" binary operator 
The operator changes the meaning of the metric, so the metric name should
be dropped. Technically this would be a breaking change, but it's also very
obviously a bug and not likely that anyone depends on it.

9aadd54786 histogram: Fix bounds of buckets returned by floatBucketIterator 
The bounds weren't really used so far, so no actual bug in the code so
far. But it's obviously confusing if the bounds returned by a
floatBucketIterator with a target schema different from the original
schema are wrong.

071f4bbea4 histograms: Fix parsing float histograms without zero bucket 
If a float histogram has a zero bucket with a threshold of zero _and_
an empty zero bucket, it wasn't identified as a native histogram
because the `isNativeHistogram` helper function only looked at integer
buckets.

2ea8df4734 histogram: Expose #12305 
Native histograms without a zero threshold aren't federated properly.

This adds a test to prove the specific failure mode, which is that
histograms with a zero threshold of zero are federated as classic
histograms.

The underlying reason is that the protobuf parser identifies a native
histogram by detecting a zero bucket or by detecting integer buckets.
Therefore, a float histogram with a zero threshold of zero and an
unpopulated zero bucket falls through the cracks (no integer buckets,
no zero bucket).

This commit also addse a test case for the latter.
