fix(net): handle string ports for Socket.connect

[seemk]

Socket.connect with a string port (e.g. socket.connect('4317', 'localhost', () => {})) was previously creating an IPC span while it should have been creating a TCP span.

For example cassandra-driver is a package that uses this form of Socket.connect.
