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
Removes request/response connection/hop headers for call resource in similar
manner as Go's reverse proxy functions. Also removes Prometheus datasource
custom call resource header manipulation in regards to hop-by-hop headers.
Fixes#60076

* Revert "Revert "Prometheus: Type and flavor configuration (#56496)" (#57552)"
This reverts commit 2432ce619a.
* Adds new fields and documentation for Prometheus datasource configuration: prometheus type, and version

* Version field will attempt to auto-detect via buildinfo API when prometheus Type is selected
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.
* 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/

* Add/modify linter exceptions

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