Evaluate all GL University content for best use (remove vs. move and/or update)

Issue

• There are just a few pages in /university/
• We're splitting the source of truth
• By having technical articles, we supply the necessity of having the /university/

Proposal

Either we incorporate the articles into doc/university, or we get rid of GL university as planned a while ago.

If we stick with the decision of removing university, I propose:

• Move the only article there (https://docs.gitlab.com/ee/university/high-availability/aws/) to doc/admin/ha/aws
• Move the glossary to doc/user/glossary/index.md
• Move the books section into the handbook
• Incorporate the content of the process section into doc/development/
• Move the Support boot camp section into doc/development/
• Move the content of training into [?] - figure out what this is about
• Incorporate the content of university/README into [?]

That's all the content we have in /university/.

Update 2/13/2018 (@mikelewis)

• Can we inventory this section, with an analysis and plan for each path and page? It could happen in here with other related path inventorying/analysis. https://docs.google.com/spreadsheets/d/1GjMIRBDwBcJe09RsUuDsFlwketS5p-kQgbuyBGYXMNM/edit#gid=1535498345
