Validation from chef

Quoted from slack:

@ici - got an announcement for you all re: our review of Cinc

We have been reviewing the community's request to to evaluate how we think Cinc is doing in honoring our Chef Trademark Policy. At this time we do not see anything in the Cinc-client Linux build which violates our trademark policy. While Chef will not be endorsing any distributions or versions of distributions of our source code except our own, we greatly appreciate the dedication of our community members in working with us to make this distribution honor the Chef Trademark Policy.

I've additionally added in some clarifications about evaluation of distros to the distribution guidelines in this pull request https://github.com/chef/chef-oss-practices/pull/266
