fix up CRD glossary term

[Bradamant3]

See PR #6594. This was a PR embarrassingly from the docs sprint at Kubecon Austin 2017. After too many revised commits and reviews from multiple competing perspectives, I figured we should merge and then fix up separately.
/assign @steveperry-53 @chenopis @heckj @zacharysarah
(mostly adding y'all to the PR so that maybe we can take a lesson learned or two as we work on process and guidelines going forward. Discuss?)

Hello everyone, and thanks @Bradamant3 for bringing this up. I agree that there's a lot of different perspectives and suggestions placed in the comments.

At the time during the docs sprint, I wasn't sure what I going up against and unsure what suggestions/comments hold more weight. Getting it fixed has been on my do list since. Like to convey that I'm still very interested in working on this. 😄
