zebra: Do not delete nhg's when retain_mode is engaged
When `-r` is specified to zebra, on shutdown we should
not remove any routes from the fib. This was a problem
with nhg's on shutdown due to their ref-count behavior.
Introduce a methodology where on shutdown we don't mess
with the nexthop groups in the kernel. That way on
next startup things will be ok.
