Define #[future] attribute to remove Future boilerplate

[la10736]

Every time an argument (test or fixture) is marked by #[future] attribute wrap type T by impl std::future::Future<Output = T>

Hey, do you have an idea on how this might be possible?
We just tried to solve this with our own type alias, but you can't use those together with impl yet.

I'm working on #111 now. Unfortunately in the last week ends I was very busy ... I'll implement this feature as the next one.

Alright that sounds great! Thanks. rstest continues to be awesome, I use it in pretty much all of my projects.

Ok, I cannot use #[asyc] because async is a keyword. Use #[future] instead

[la10736]

Basic implementation is in place.

What's missed:

• Integrations test for rstest
  • Cases
  • Values
  • Single
• Unit tests
• Discard invalid cases like impl or some other strange types
• Implement explicit lifetime substitution for references
• Little refactoring
• Documentation
• Changelog

I've released 0.9.0 yesterday.

Working perfectly for us, thanks!
