GitLab/Gerrit to GitLab

This is intended as a concise reference document for experienced users of Gerrit, explaining how concepts and workflows map to GitLab features, and indexing into the rest of our guides as well as upstream docs.

Proposed table format:


 * So you have a Gerrit patchset
 * Working with branches and creating merge requests
 * Merge options


 * So you want to review code
 * +2 code/-2
 * Reviewing code using merge requests
 * Markdown, suggestions, etc.
 * fix someone's change


 * So you have a code review dashboard


 * So you want tests to (re)run


 * So you want to see if something is merged


 * So you want to know who merged this


 * So you want to backport a change


 * So you want to group some changes
 * In a project
 * Across projects


 * So you want someone to review your code
