The GWT UI and other parts of Gerrit still rely on the in-memory
cache for rendering the project list.
This is the first step that moves some use-cases to the QueryProjects
engine: full list without filters and showing only the active and readonly
projects.
All other existing use-cases are still based on the in-memory
cache and are going to be addressed in the follow-up of this change.
With regards to filtering by project name substring, it is not
implemented on top of the secondary index because of Issue 10446.
