Expose Mixlib::ShellOut's streaming in Utils
Expose Mixlib::ShellOut's streaming in Utils

taste-tester has a `run` mode that runs chef and streams the output in
real time. Rather than doing all this work manually, just enable users
of `BetweenMeals::Util` to use Mixlib::ShellOut's 'stream' options by
passing them through.

See https://github.com/facebook/taste-tester/pull/131 for a use-case.
