Add support for hiding endpoints with annotation

[trycatchblock]

Similar to #475 , Can we add support for hiding endpoints with annotation?

Yes, this is badly needed.

Just curious: what is the rationale behind this?

I implemented something similar in my own code since I did not want the api-docs.json to show up as part of the swagger description itself. However I wonder what the more general user case that make this "badly needed" is...

Hi, this is on the server code, not in the spec--it makes the auto-generated swagger description hidden for a particular field.

There are many reasons to do this, some could be with how the framework is parsed by the swagger framework.
