Deprecate interact annotation syntax

[jasongrout]

Annotations now have a somewhat "official" syntax in python, courtesy of https://www.python.org/dev/peps/pep-0484/. I propose we deprecate the annotation syntax for interacts.

The PEP does say:

Note that this PEP still explicitly does NOT prevent other uses of annotations, nor does it require (or forbid) any particular processing of annotations, even when they conform to this specification. It simply enables better coordination, as PEP 333 did for web frameworks.

However, I think the annotation syntax doesn't add enough value and our decorator-based syntax is not widespread enough to maintain it.

@SylvainCorlay, @ellisonbg, and others: thoughts?

Okay, plan is to deprecate it in 7.0, remove it after some time has passed (a year?)
