Use logical CPUs instead of physical by default (#2391)
Some reasons to prefer logical count as the default:
- Chips reporting many logical CPUs vs physical, such as via
hyperthreading, probably know better than us about the workload the CPUs
can handle.
- The logical count (`num_cpus::get()`) takes into consideration
schedular affinity, and cgroups CPU quota, in case the user wants to
limit the amount of CPUs a process can use.
Closes #2269
