Improve findSetMatches to support concatenation. 
This improves how we find `SetMatches` for regexp. Notably it allows to support concatenation
such as `api_(v1|prom)_push` for which the resulting set matches are `api_v1_push` and `api_prom_push`.

I had to support characters classes too since the syntax may try to optimize alternates with them.

In the end the code is also more robust than the previous implementation relying on the stringyfied version of the regexp.

This could be upstreamed later.

Optimise query_range by computing join signatures just once (#9360) 
* Add benchmark case for many-to-one join

Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

* query_range: compute join signatures just once

For an expression like `a + on(p,q) b`, extract the `p,q` part from each
series once, instead of re-computing at every step of the range.

Although there was a cache, computing the key by concatenating all
labels was expensive.

Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

* Optimise topk where k==1

In this case we don't need a heap to keep track of values; just a single
slot is fine.

Simplify the initialization of the heap: since all cases start off as a
single-item heap we can just assign the value directly.

* Allow at least one slot in results for topk, quantile

k isn't set for quantile, but we need space to start collecting values

We have been Puppet user for 10 years and we are users of
https://github.com/camptocamp/prometheus-puppetdb-sd

However, that file_sd implementation contains business logic and
assumptions around e.g. the modules which you are using.

This pull request adds a simple PuppetDB service discovery, which will
enable more use cases than the upstream sd.
