Add examples of iteration to the handbook
Overview
We discussed the importance of iteration during the Product Meeting on 2019-11-05. Highlighting that this is an approach that's "not intuitive to many incoming PMs", we've also started recurring office hours with Sid to brainstorm approaches to things we're building now that emphasize iteration.
I think it may also be helpful to document examples of things that we've shipped in the past that were highly iterative.
Proposal
Come up with 3-5 issues/epics that demonstrate iteration and add them to https://about.gitlab.com/handbook/product/#iteration.
