Zakhar Bessarab 06947c2685 vmagent: add support of HTTP2 client for Kubernetes SD (#7114) ... ### Describe Your Changes Currently, vmagent always uses a separate `http.Client` for every group watcher in Kubernetes SD. With a high number of group watchers this leads to large amount of opened connections. This PR adds 2 changes to address this: - re-use of existing `http.Client` - in case `http.Client` is connecting to the same API server and uses the same parameters it will be re-used between group watchers - HTTP2 support - this allows to reuse connections more efficiently due to ability of using streaming via existing connections. See this issue for the details and test results - https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5971 ### Checklist The following checks are **mandatory**: - [ ] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). --------- Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> Co-authored-by: Roman Khavronenko <roman@victoriametrics.com> (cherry picked from commit eefae85450)		2024-10-08 10:37:48 +02:00
