Get-vNUMA-config.ps1

function Get-vNUMA-config{
<#
.SYNOPSIS
    Retrieve the vNUMA config for all running VMs from a host
.DESCRIPTION
    The function retrieves the vmware.log of all powered on VMs and greps for vNUMA relevant dictionary and log entries. The equivalent of the ASH one-liner:
    "vmdumper -l | cut -d \/ -f 2-5 | while read path; do egrep -oi "DICT.*(displayname.*|numa.*|cores.*|vcpu.*|memsize.*|affinity.*)= .*|numa:.*|numaHost:.*" "/$path/vmware.log"; echo -e; done"
    Todo: make everything into proper objects (get adv settings for options, parse numahost log output), clean up temp space
