Initial implementation for real time job view

Added the needed keys and paths to a new entity, BuildDetailsEntity.
Not renaming BuildEntity to BuildBasicEntity on explicit request. Most
code now has test coverage, but not all. This will be added on later
commits on this branch.

Resolves gitlab-org/gitlab-ce#31397
