[RichardoMrMu]

following this issue #17794, and #10582 this issue ([P2] Make it work with tracing too (there's some request level stats that tracing needs, like queue time, ttft). These request level metric should be possible to be surfaced in v1 too.). I make engine v1 to generate model tracing span.

You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.
