* Fix federation test

While we have added some logic to the promql engine to keep it backwards
compatible and have a 5 minute loopback by default, the web/ package is
likely to really be internal to Prometheus and we should not add the
same kind of heuritstics here.

Julien Pivotto 9adad8ad30 Remove MaxConcurrent from the PromQL engine opts (#6712) 
Since we use ActiveQueryTracker to check for concurrency in
d992c36b3a it does not make sense to keep
the MaxConcurrent value as an option of the PromQL engine.

This pull request removes it from the PromQL engine options, sets the
max concurrent metric to -1 if there is no active query tracker, and use
the value of the active query tracker otherwise.

It removes dead code and also will inform people who import the promql
package that we made that change, as it breaks the EngineOpts struct.

Brian Brazil 38d32e0686 Don't sort postings if we only have one block. 
Sorting the heads postings can be quite slow.
We only need sorted series when merging with another
querier, so only sort then.
This will make big queries that only touch the head faster,
though queries that touch both the head and a block will still
be the same speed. This probably won't help much with graphing
unless the range is under an hour, however it should make most
recording rules faster.

Add gaurantee that remote read streaming produces sorted series.

PromQL benchmarks for histograms show only 2-3% improvement, but
they're only over 1k series.

Tobias Guggenmos f5eed7ae0a PromQL: Fix panic in parser (#6650) 
Fixes #6649.

The crash is fixed here, was caused because some  AST sanity checks were performed on the syntax tree while assembling it. In case of previous parsing errors this could lead to undefined behaviour.

The fix is to move the checks to the typechecking phase, which runs only when a syntax tree was assembled without there being parsing errors.

There are other places, where similiar checks are performed while assembling the syntax tree. It might be a good idea to move those to the typechecking phase, too. Should I do this in the same or a separate PR?

Tobias Guggenmos 6534ce843f PromQL: Use a sync.Pool for the generated parser structure (#6591) 
* PromQL: Use a sync.Pool for the generated parser structure

The generated PromQL parser allocates a struct about 4kb in size on every run.

This puts a high load on the garbage collector.

To reduce that load, a sync.Pool is used to recycle these structures.

On small queries this makes parsing 2-3 times faster.

Julien Pivotto 577e738986 Cleanup PromQL functions (#6551) 
* Cleanup PromQL functions
