Summary: Never really liked this code. Before this change, calls to connect were blocking. Because of this, we had to make use of promises and a bit of really not that good-looking code. So, this change makes connect non-blocking meaning that we make full use of our event handler. These changes contain: - CSR is not getting generated after each failed attempt. - Connect is no longer blocking. - Do not report events via the handler when explicitly disconnecting.
