[POC - Behat] Add EzBehatExtension and ArgumentResolver

[miguelcleverti]

As decided BehatBundle is to be deprecated and separated between the kernel and platformUI bundle. The idea is to make the Behat easier to maintain, having less repo dependencies should help releases and versions also.

This PR moves the EzBehatExtension and AnnotationArgumentResolver into the kernel. This is used to inject into behat the necessary services. Since this is to be used by most contexts it should be in the kernel.

+1 about the code itself (it has been reviewed before).

But could you please describe the feature a bit better in the PR ? Not everybody has been involved in this. We should also consider documenting it somewhere, in the same PR. Could you take care of it ?

But please before merging, make sure you bump branch-alias in composer.json to 6.3.x-dev if it hasn't been done at that time.

Ping @joaoinacio and @andrerom.

@bdunogier I added the BehatExtension/ArgumentResolver docs to the PR and also bumped the branch-alias version. I will include the rest of the docs in their respective PR.
