LU-10391 lnet: migrate full LNet NI information collection

Fill in the rest of the LNet NI state to report to user land. This
mostly covers the stats information of the NI and LND specific
tunables. To handle the LND specific tunables we need to reorder
the code to send an updated key table. With the additional
information I found status wasn't properly set and the nesting
for was properly set for multiple NIs per NET. This is now fixed.
