Extensibility, running custom logic in tests or contributing plugins

[guillaume-fr]

Hurls supports aws signature schemes but they are plenty other custom auth schemes and complex flow that cannot be expressed in a regular hurl file. Some might be doable with some scripting before hurl but other things relies on content of requests and cannot be done in advance.

Would be nice to be able to extend hurl, without forking it, to add custom auth schemes, maybe with request/response handlers or other ways to inject custom logic. For instance, postman allows executing Pre-request and Post-request code. That or a plugin system would be nice.
