Review Comment:
OK. Please add some comments to illustrate our special scenarios like
`log_prefix()`:
Otherwise, using `get_char_str` by mistake may lead to some bugs:
```
// The size of hosts are more than 8.
std::vector<host_port> hosts;
......
std::vector<const char *> strs;
for (auto &e: hosts) {
strs.push_back(e.get_char_str());
}
```
