Remote-write creates several shards to parallelise sending, each with
its own http connection. We do not want them all combined onto one
socket by http2.

scrape: Remove implicit fallback to the Prometheus text format
Remove implicit fallback to the Prometheus text format in case of invalid/missing Content-Type and fail the scrape instead. Add ability to specify a `fallback_scrape_protocol` in the scrape config.

promql: Fix stddev/stdvar when aggregating histograms, NaNs, and Infs
Native histograms are ignored when calculating stddev or stdvar.
However, for the first series of each group, a `groupedAggregation` is
always created. If the first series that was encountered is a histogram
then it acts as the equivalent of a 0 point.
This change creates the first `groupedAggregation` with the `seen` field set to `false` if the point is a
histogram, thus ignoring it like the rest of the aggregation function does. A new `groupedAggregation`
will then be created once an actual float value is encountered.
This commit also sets the `floatValue` field of the `groupedAggregation` to `NaN`, if the first
float value of a group is `NaN` or `±Inf`, so that the outcome is consistently `NaN` once those
values are in the mix.
(The added tests fail without this change).

The `info` function is an experiment to improve UX
around including labels from info metrics.
`info` has to be enabled via the feature flag `--enable-feature=promql-experimental-functions`.
This MVP of info simplifies the implementation by assuming:
* Only support for the target_info metric
* That target_info's identifying labels are job and instance
Also:
* Encode info samples' original timestamp as sample value
* Deduce info series select hints from top-most VectorSelector

Go's sorting functions can re-order equal elements, so the strategy of
sorting by the fallback ordering first does not always work.
Pulling the fallback into the main comparison function is more reliable
and more efficient.

* Make rate possible non-counter annotation consistent
Previously a PossibleNonCounterInfo annotation would be left in cases
where a range-vector selects 1 float data point, even if no more points
are selected in order to calculate a rate.
This change ensures an output float exists before emitting such an
annotation.
This fixes an inconsistency where a series with mixed data (ie, a float
and a native histogram) would emit an annotation without any points.
For example,
```
load 1m
series{label="a"} 1 {{schema:1 sum:10 count:5 buckets:[1 2 3]}}
eval instant at 1m rate(series[1m1s])
```
Would have a PossibleNonCounterInfo annotation.
Wheras
```
load 1m
series{label="a"} {{schema:1 sum:10 count:5 buckets:[1 2 3]}} {{schema:1 sum:15 count:10 buckets:[1 2 3]}}
eval instant at 1m rate(series[1m1s])
```
Would not.
