DEVPROD-5483
Description
By default go doesn't see its number of CPUs is limited by a cgroup. Including this library will set GOMAXPROCS to the appropriate number of CPUs. noops if running outside a container.
Testing
In staging it limited to 1 CPU, which is consistent with the CPU limit. Interestingly, the CPU time we used actually went down 🤔 .
On my laptop and on a Linux spawn host it logged:
meaning it left the value unchanged because there was no limit set.
