Document wiki architecture
Problem to solve
The code related to wikis is not very well documented, and with the work on group wikis we've also made a number of changes.
Further details
Proposal
We should document how the wiki feature is architected, and how the different components interact with each other:
- https://gitlab.com/gitlab-org/gitlab
- https://gitlab.com/gitlab-org/gitaly
- https://gitlab.com/gitlab-org/gollum-lib
- https://gitlab.com/gitlab-org/gitlab-gollum-rugged_adapter
