API and CLI option for enabling network multiqueue on kubevirt platform nodepools

Based on the perf scale team's results, enabling multiqueue when jumbo frames (MTU >=9000) can greatly improve throughput. as see by comparing slides 8 and 10 in this slide deck, https://docs.google.com/presentation/d/1cIm4EcAswVDpuDp-eHVmbB7VodZqQzTYCnx4HCfI9n4/edit#slide=id.g2563dda6aa5_1_68
However enabling multiqueue with small MTU causes "throughput to crater".

This task involves adding an API option to the kubevirt platform within the nodepool api, as well as adding a cli option for enabling multiqueue in the hcp cli (new productized cli)
