Plugins: Automatically forward plugin request HTTP headers in outgoing HTTP requests (#60417) 
Automatically forward core plugin request HTTP headers in outgoing HTTP requests. 
Core datasource plugin authors don't have to specifically handle forwarding of HTTP 
headers, e.g. do not have to "hardcode" the header-names in the datasource plugin, 
if not having custom needs.

Fixes #57065

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

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.
