NioServer: retain links by address string to minimize resource leak (#3525)

Every time a client connects, the NioServer will retain the link against
the InetSocketAddress object. If the same agent/client reconnects, it
will grow older links over time and in case of denial of service attack
or a client/script/monitoring-service reconnecting aggressively against
port 8250 will cause the `_links` weak hashmap to grow over time and
very quickly.

The fix will ensure that only one Link gets weakly retained for an
incoming client based on its address string.
