Some open questions of concern, but also seems some files were checked in that shouldn't be (and I'll have to review again anyway).

Overall, LGTM.

I think the azure_core benchmarks were fine. Probably just one function wasn't worth keeping, but the others were.

Besides, you'd have needed to fix azure_core's Cargo.toml to remove the benches, but I think put them back. At best, remove the HTTP rest from benchmarks but leave the rest. I updated it in #3190
