Remove Infinispan binary stores

Since ModeShape 5.0 will not use Infinispan anymore, the current Infinispan-based binary stores should be removed. The file and database binary stores are still available.

Users migrating from 4.x or 3.x can use the backup and restore functionality to backup their exiting repository (including existing binary data) and restore it into a 5.0 repository, even if the new repository uses a different type of binary store.
