Support multiple numa nodes per core

[Macks]

I am on stx7. While adding a dell r7415 as worker node, sysinv agent fails to get inventory.

This is due to sysinv unable to work with multiple numa nodes per socket. It errors out on sysinv/agent/node.py#427 with uncaught OSError and cannot get host memory because it expects dir /sys/devices/system/node/node0/hugepages, which may not exist (mine is on node1).

With chiplet design being more common these days, it makes sense to not assume 1 numa node per socket.

Workaround: modify bios memory interleaving so it presents a single numa node per socket, or if bios doesn't support that like mine, add `numa=off` to grub boot params. Both results in decreased performance.
