[NETNS][IPV6]: inet6_addr - check ipv6 address per namespace
When a new address is added, we must check if the new address does not already exists. This patch makes this check to be aware of a network namespace, so the check will look if the address already exists for the specified network namespace. While the addresses are browsed, the addresses which do not belong to the namespace are discarded.
