feat: add network topology functions

[fcgxz2003]

Construct the network topology by storing probes in redis.
There are three types of storage structures in redis:

network-topology:src:dest (hash)
Store averageRTT, createdAt, updatedAt of multiple probes from src to dest.
probes:src:dest (list)
Store probes list from src to dest.
visit-times:src (string)
Store visit times of src in this network topology, in other word, the number of times src is probed.
