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
