Ruby

Adds support for creating state machines for attributes on any Ruby class

IssuableFinder#count_by_state

We often get counts for each state by running a query per state, and
counting those results. This is typically slower than running one query
(even if that query is slower than any of the individual state queries) and
grouping and counting within that query.
