Make orphan binaries GC scalable

      Description

      The orphan binaries GC can take a long time (days) when the Nuxeo Platform is storing a large number of binaries (millions) in its file storage.

      Even though orphan binaries GC is considered a maintenance operation, some users need to run it often e.g. when the Nuxeo Platform is used as a temporary storage therefore does not need a large file storage.

      Several improvements can be provided depending on the user's need:

      • the initial list of digests retrieved from the database could be splitted and each part execute in its own thread,
      • make the orphan binaries GC synchronous (see NXP-28523) (interesting when the Nuxeo Platform is used as a temporary storage),
      • maintain a reverse index referencing the document(s) using the binary
