shouldn't this test be updated to opt-in for push, now that it is disabled by default ?

sure, fixed
note that the test doesn't work, but we skip it
I prefer keeping it this way so that we are reminded about it in the future :)

This PR was merged into the 4.3 branch.Discussion----------[HttpClient] Re-enable Server Push support| Q | A| ------------- | ---| Branch? | 4.3| Bug fix? | no| New feature? | no <!-- please update src/**/CHANGELOG.md files -->| Deprecations? | no <!-- please update UPGRADE-*.md and src/**/CHANGELOG.md files -->| Tickets | n/a <!-- prefix each issue number with "Fix #", if any -->| License | MIT| Doc PR | n/a#33444 disabled Server Push support for the CURL implementation, but `HttpClient::create()` has been forgotten and override this parameter, consequently for most users Server Push wasn't disabled at all. The root issue affecting the tests are actually a misconfiguration of Akamai servers (we need our own test infrastructure).According to my testing, Server Push support works very smoothly. Also, it can cause problems only if the server actually pushes responses (which is still rare).So I propose to re-enable Push Support everywhere.Commits-------8483842 Re-enable push support for HttpClient

For the test cases,https://http2-push.io is down, let's use Akamai instead
This PR now considers the proxy settings before accepting a pushed response.
It also splits the responsibility of dealing with accepting pushed responses in method
acceptPushForRequest.The logic in this method could also be delegated to a userland callback passed as an option. Let's wait for someone with an actual use case before adding the option.
This PR also disables HTTP/2 PUSH by default because it is not stable: locally, with the latest curl version, enabling this on a server that pushes things fails with
