Create a unique group ID to map the sFlow info when offloading sFlow
action to TC. When showing the offloaded datapath flows, translate the
group ID from TC sample action to sFlow info using the mapping.

This commit doesn't change any functionality, it just performs the
following refactor work:
a. consolidates the old build_ovn_lbs(), build_lrouter_lbs() and
build_ovn_lr_lbs() functions into a single function, build_lbs(),
that builds all the load balancer port-independent information.

Today dpif-netdev considers PMD threads on a non-local NUMA node for

On typical servers with both physical ports on one NUMA node, this

In this scenario we have one VM each on NUMA0 and NUMA1 (VM1 is on NUMA0, VM2

Without cross-numa-polling, VM/VHU queue traffic is evenly distributed based on
