Jesus Vazquez 51f26e0cba Necessary changes to make the merge work 
This commit disables some unused workflows on our CI.

Also uses grafana/regexp instead of regexp which is blackisted.

Also updates head_test TestHeadReadWriterRepair increasing
ChunkWriteQueueSize to 1 so that the chunk disk mapper uses the async
queue. This seems to be default behaviour in upstream prometheus and
without this option our test fails.

Allow downstream projects to use faster regexp (#10251) 
* Add benchmark for FastRegexMatcher

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

* Use modified regexp package with optimisations

See https://github.com/grafana/regexp/tree/speedup#readme

Includes the following changes proposed upstream:
* [regexp: allow patterns with no alternates to be one-pass](https://go-review.googlesource.com/c/go/+/353711)
* [regexp: speed up onepass prefix check](https://go-review.googlesource.com/c/go/+/354909)
* [regexp: handle prefix string with fold-case](https://go-review.googlesource.com/c/go/+/358756)
* [regexp: avoid copying each instruction executed](https://go-review.googlesource.com/c/go/+/355789)
* [regexp: allow prefix string anchored at beginning](https://go-review.googlesource.com/c/go/+/377294)

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

* Use regexp code identical to upstream Go

Change `grafana/regexp` import to use `main` branch.

This means Prometheus is not using the proposed optimisations, but
downstream users of Prometheus code are able to `replace` the library
with the `speedup` branch which does.

beorn7 c954cd9d1d Move packages out of deprecated pkg directory 
This creates a new `model` directory and moves all data-model related
packages over there:
  exemplar labels relabel rulefmt textparse timestamp value

All the others are more or less utilities and have been moved to `util`:
  gate logging modetimevfs pool runtime
