Setup mitmproxy

What is mitmproxy? It is a free and open source interactive HTTPS proxy. It is a console tool that allows interactive examination and modification of HTTP traffic. It differs from mitmdump in that all flows are kept in memory, which means that it's intended for taking and manipulating small-ish samples. It has a web interface that allows you to browse the traffic that has been intercepted.
