This header was copied to the upstream request, causing connection churn towards Pyroscope, which can be quite bad on the CPU when using TLS. Do not copy the `Connection` header from the incoming request to fix this issue. Additionally, `pyroscope.write` had a single `http.Client` used for forwarding data from `pyroscope.receive_http`, which may not work if multiple endpoints are configured with different options. To fix this, store a `http.Client` for each endpoint. --------- Co-authored-by: YusifAghalar <[email protected]> Co-authored-by: Piotr <[email protected]> Co-authored-by: Sam DeHaan <[email protected]> Co-authored-by: Craig Peterson <[email protected]> Co-authored-by: Marc Sanmiquel <[email protected]> Co-authored-by: Sergei Nikolaev <[email protected]> Co-authored-by: William Dumont <[email protected]> Co-authored-by: Sam DeHaan <[email protected]> Co-authored-by: Gergely Madarász <[email protected]>

PR Description
There was a race condition where the http service -> ui service required the remotecfg service to have at least run the first line of its Run() function, but they are all started in parallel in goroutines so there was no guarantee of consistent ordering. See #2157 for a follow up on that concern, but this PR fixes it by only looking to resolve the remotecfg's Data object during HTTP resolution time, where the service should definitely be available.
