Diagrams in Geo docs to explain internal process and error handling
Came up in conversation with @vsizov earlier today that it would be helpful for developers getting up to speed on the geo codebase to have a diagram in the docs that explains some of how Geo works with a worker that is scheduled by cron, this cursor is a daemon, how they pick tasks, how they report errors, etc.
Valery estimates this might take half a day to do right. @nick.thomas for some odd reason I thought perhaps we already had something like this? cc @jramsay
