💛 - Coveralls

Pick between async-file or fs-extra in the project but not both.

[justinwilaby]

It appears that including fs-extra will introduce 2 dependencies that do the same thing into our production code. async-file is used currently and it makes sense to pick one and standardize on it. fs-extra is my first choice but async-file is fine too.

Thanks Justin for the review! I'm not sure where you're seeing the dependency on async-file. fs-extra appears to be being used by the bot framework, so we should probably keep that.
The new set of bits is adoption of new ms-rest stuff which doesn't appear to have a async-file dependency (?).

It looks like the unit tests were updated but coveralls is reporting the entire error block missing coverage. Any ideas what happened here?

Nice catch, I checked in fixed tests!

LGTM, but I was also the last person to touch this PR 😄 @justinwilaby, @daveta or @cleemullins can you take a look?

All feedback addressed, looking to merge.
