[chef] CHEF-3930: Run apt-get update automagically if apt-get install fails

[Bryan McLellan < >]

Should the apt provider try to run apt-get update if :install fails?

We talked about this a bunch at code review [1] today, starting at
22:45. http://www.youtube.com/watch?v=8pOd8NzmKIY

+ This happens all the time, thanks man.
- I told Chef to install a package, not update my sources! Get off my lawn!

In all seriousness, it's a pretty interesting boundary between Chef
being pretty helpful versus Chef being strict about its role. There
isn't a solution here that pleases everyone, but I'm curious about any
other opinions.
