Kyle Brandt 6126f56ef0 Prometheus: Do not drop errors in streaming parser (#57698) 
- Fixes #57692
- and also takes care of #42776 when using the streaming parser, not an ideal fix for #42776 but makes explore work better I think. https://github.com/grafana/grafana/issues/57365 might be a better longer term solution

Kyle Brandt 27288276a2 Prometheus: Restore FromAlert header (#55255) 
This restores the FromAlert header to prometheus for Grafana managed alert Queries. 

It does this by reverting "Prometheus: Remove middleware for custom headers (#51518)" , but also changing it so it is only the FromAlert header.

This reverts commit 2372501368.

Emil Tullstedt b287047052 Chore: Upgrade Go to 1.19.1 (#54902) 
* WIP

* Set public_suffix to a pre Ruby 2.6 version

* we don't need to install python

* Stretch->Buster

* Bump versions in lib.star

* Manually update linter

Sort of messy, but the .mod-file need to contain all dependencies that
use 1.16+ features, otherwise they're assumed to be compiled with
-lang=go1.16 and cannot access generics et al.

Bingo doesn't seem to understand that, but it's possible to manually
update things to get Bingo happy.

* undo reformatting

* Various lint improvements

* More from the linter

* goimports -w ./pkg/

* Disable gocritic

* Add/modify linter exceptions

* lint + flatten nested list

Go 1.19 doesn't support nested lists, and there wasn't an obvious workaround.
