fix(test_util): make hyper server single-threaded (#8951)

Browse source 
Use Tokio's single-threaded scheduler. The hyper server is used as a
point of comparison for the (single-threaded!) benchmarks in cli/bench.

We're not comparing apples to apples if we use the default
multi-threaded scheduler.

This drops the requests/sec from 284k to 130k on my 12 core Ryzen 5
system. That still leaves a 50k gap for us to close. Working on it!
