Feature request: Support for collection level configurations

It would be nice to be able to set some options (e.g. authentication, or ssl certificate checking) at collection or folder level instead of at request level, having those options automatically inherited by child objects (requests, other subfolders).

Totally agree this would be an awesome feature.

I was considering some kind of system where you can create a "base" YAML files in directories, and those would be used to build up the default values when a new request is created.
