benchmark on docker on mac: could not find integer "NUMA node(s)"

I'm trying to run a benchmark and use docker on Mac as the target VM. This is my static VM config:

```
static_vms:
- &vm1
ip_address: sshserver ## docker on mac
user_name: root
ssh_private_key: /tmp/key

some_benchmark:
vm_groups:
default:
static_vms:
- *vm1
```

After executing the benchmark, i get the following error (omitted earlier logs). The benchmark progress until the point where lscpu command is trying to parse out "numa nodes(s)". Im no an expert in this area but I do not think Numa applies to Mac which I think is the reason why the numa nodes output is missing from lscpu on docker. Any potential workarounds? And why is numa_node_count is collected in linux_virtual_machine? The reason I ask is that the only benchmarks taking advantage of it are linux_benchmarks/hpcc_benchmark.py and redit_enterprise I believe? Any reason to collect this for all linux benchmarks?
