Ensure cgroups cpu.weight is within [1, 10_000]

[NathanFlurry]

Problem

Runs with >= 1 CPU core would fail with this error:

time="2023-11-15T19:01:22Z" level=error msg="runc run failed: unable to start container process: error during container init: error setting cgroup config for procHooks process: failed to write \"38144\": write /sys/fs/cgroup/system.slice/rivet-573e639a-7e66-6d43-3eee-c0fcd98c9cdf/cpu.weight: numerical result out of range"

The resulting CPU weight would be larger than 10,000.

Solution

The CPU weight is now converted from millicors to centicores (i.e. divide by 10) so 32 cores is still less than 10,000 shares.
