network: dhcp6: manage assigned downstream prefixes by using Hashmap
When a system has thousands of downstream interfaces, previously the
total cost of finding free subnet ID was O(n^2), where n is the number
of downstream interfaces.
This makes assigned prefixes are managed by Manager with Hashmap. So,
the cost becomes O(n log n).
