Add direct support for ZAP

[psiinon]

Just a suggestion ;)
I noticed #97 but direct support might be more flexible.
Note that ZAP is already available as docker images: https://github.com/zaproxy/zaproxy/wiki/Docker
Ping me if you need any help or guidance with this.

@psiinon Cool! Could we talk somehow about your zap SaaS solution (maybe slack)?

[psiinon]

Sure :) I talked about it at AppSec EU recently: https://www.youtube.com/watch?v=LJIoyx405bw (from around 31 mins in)
Could have a video call if you like, but probably not right now as I'm on holiday ;)
