promql: Organize legacy tests into appropriate files (#7989)
* Separate tests into:
** Aggregators
** Functions
** Operators
** Selectors
* Remove simple files and place tests into other files.
* Eliminate some of the _over_time tests since there are already plenty of
  edge cases present in the functions.test file.

Relates to #740

David King 6286c10df0 Fix OOM when a large K is used in topk queries (#4087)
This attempts to close #3973.

Handles cases where the length of the input vector to an aggregate topk
/ bottomk function is less than the K paramater. The change updates
Prometheus to allocate a result vector the same length as the input
vector in these cases.

Previously Prometheus would out-of-memory panic for large K values. This
change makes that unlikely unless the size of the input vector is
equally large.

Brian Brazil 16690736ab Add count_values() aggregator.
This is useful for counting how many instances
of a job are running a particular version/build.

Fixes #622

Brian Brazil 3b89616d82 Allow on, ignoring, by and without wit empty laberls.
This offers new semantics in allowing on() for matching
two single-element vectors with no known common labels.
Previosuly this was often done using on(dummy).

This also allows making it explict that you meant
to do an aggregation without labels via by().

Fixes #1597.

Brian Brazil 9d0112d7cf Add without aggregator modifier.
This has the advantage that the user doesn't need
to list all labels they want to keep (as with "by")
but without having to worry about inconsistent labels
as when there's only one time series (as with "keeping_common").

Almost all aggregation should use this rather than the existing
two options as it's much less error prone and easier to maintain
due to not having to always add in "job" plus whatever other common
job-level labels you have like "region".
