Bryan Boreham a5a4eab679
Storage: reduce memory allocations when merging series sets (#12938) 
Instead of setting to nil and allocating a new slice every time the
merge is advanced, re-use the previous slice.
This is safe because the `currentSets` member is only used inside member
functions, and explicitly copied in `At()`, the only place it leaves the
struct.

Add warnings (and annotations) to PromQL query results (#12152) 
Return annotations (warnings and infos) from PromQL queries

This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations".

Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future.

The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms).

The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later.

Another TODO is to take annotations into account when evaluating recording rules.
