**Expected behavior**

-torcontrol should try to resolve a hostname if it is given

**Actual behavior**

The hostname is passed as an ip so the connection fails

```
2021-06-13T20:35:54Z tor: Error parsing socket address mynode.local:9051
2021-06-13T20:35:54Z tor: Initiating connection to Tor control port mynode.local:9051 failed
```

**To reproduce**

Add ```127.0.0.1 mynode``` to /etc/hosts and pass -torcontrol=mynode:9051 as an argument. The connection fails. Try with -torcontrol=127.0.0.1:9051 and it works.
