feat: manual-discovery with node tags

[giangndm]

This merge implement a discovery mechanism which use tag for finding which node should be connected to.

• Each node has multi string local-tags, and set to multi-hash-map: SetH(hash(tag), node_id, node_addr).
• Each node has multi string connect-tags, and sub to multi-hash-map: SubH(hash(tag)).

By that way, each node will received node_id and node_addr of all node which interested by connect-tags, and using the addr to connect to.
