Add chef-utils gem with various recipe DSL helpers

This is the implementation of [RFC-087](https://github.com/chef-boneyard/chef-rfc/blob/master/rfc087-distro-sugar-helpers.md)
although some of the specifics have been iterated on and changed.

The documentation will be in the [README.md](https://github.com/chef/chef/tree/master/chef-utils/README.md) once this is merged.

While this PR mostly moves chef-sugar utilities into core-chef via this chef-utils gem, the scope of the chef-utils gem
should be considered larger than just that. As an example this PR moves the Mash class into this gem for reuse in ohai
as well.
