http proxy server: don't work as an actual proxy

[jstucke]

As #43 pointed out, it is not a good idea for a honeypot to work as an actual proxy server, because this can be misused in a malicious way.

This PR tries to solve this by returning a dummy website instead of the actual website and was based on #44.

• adds a dummy website and adds it to the installation
• returns the dummy website instead of the actual website in http_proxy_server.py
• adds a wait time to fix problems with a flaky test

resolves #43

Thank you for reviewing this item.
Could we have the dummy website read from a local file? And it would be great to make the file path configurable.
Sorry I don't know enough of this project's code to implement that.

Yes that shouldn't be much of a problem. I will look into it

It seems to work already on the fork but it will probably also get merged back here soon
