- missing lock here.
- maybe it is better to directly copy out the address instead of the key to avoid unnecessary existence check in the latter code.

This structure will add other members in next version.
1. When receive address message save the addresses in address list. 2. If the connection is less than MaxOutboundCnt, select addresses from address list and connect them. 3. When receive getaddr request, randomly select some address and send addr response. At most send 8 address. Signed-off-by: Jin Qing <1091147665@qq.com>
If the connection is less than MaxOutboundCnt, the node will pick peers from address list and connect them. So we don't need reconnect now. Signed-off-by: Jin Qing <1091147665@qq.com>
If the connection more than max connect peers, disconnect one node. Signed-off-by: Jin Qing <1091147665@qq.com>
If address list less than 1000 send getaddr request Signed-off-by: Jin Qing <1091147665@qq.com>

It seems that the upper two function signatures have opposite function body.
Judge whether the peer is bad before connect it. If it is bad won't connect it. Signed-off-by: Jin Qing <1091147665@qq.com>
