Add DI container support for contextual runners about lightbdd

[aidapsibr]

Hey, you might want to check out SpecFlows BoDi container for a default integrated DI container. I am using it in psibr/REstate successfully with external DI support. It is pretty limited, but also easy to modify as I did to support IEnumerable resolutions.

Hello @psibernetic . I have just recently came to this ticket to think how to implement it.
Thanks for the hint - I have took a look at the BoDi implementation, however decided to build some abstractions in LightBDD itself to support container scoping (for contextual scenarios and steps) and integration with other DI containers.

I have got a basic DI working which will be shipped with LightBDD 2.4.0, and added LightBDD.Autofac project with sample integration with Autofac. Hopefully, over the time there will be more integrations with other people favourite DIs.

There is still a lot of docs and samples to be written before shipping 2.4.0, but it should appear soon :)

Very good sir, looking forward to it.

The feature has been implemented on develop branch and will be released with LightBDD 2.4.0
