Feature: Support for a simplified ginkgo outline output w/out setup containers

[Dannyb48]

Would you be willing to support a feature where in the ginkgo outline command we could pass a --simple flag that would allow us to strip away any of the setup containers from the outline output?

The idea is to create a more simplified output that is similar to a BDD style spec output that I can present to my non-technical stake holders. Since the setup containers don't really have any crucial text it would be great to strip that out.

I have post-processing code to strip this out of when I capture the outline output but it would simplify my processing if we pushed this into the outline command.

hey @Dannyb48 - i'm of two minds. on the one hand, the elegance of these kinds of machine readable formats is that downstream users can post-process them (as you've done) to fit their needs so we don't have to add lots of complexity/one-offs to Ginkgo. on the other hand, i get that it would be simpler/easier for you if the tool Just Worked™.

with that said, I think i'd want something that's a bit more well-defined than --simple. perhaps --without-setup-nodes or --only-textual-nodes

Thoughts? if you're up for writing the PR I think something like --without-setup-nodes or --only-textual-nodes would be fine.
