If you specify a UnixSocket, your HostName is ignored

I think instead of connectHost and connectPort, the connection details should include connectAddr which is a SockAddr. This would help avoid confusion about what connectHost does or whether it needs to be set correctly when you're connecting via Unix socket.

Merging #189.

We can further discuss here about how to take this forward with maintaining backward compatibility for the current users. Another idea is to make the connectHost as Maybe and return error on Nothing when connectPort is not Unix Socket.
