Summary: Add the basic BackingStore interface, plus a NullBackingStore implementation that always returns null. This updates the ObjectStore to query the BackingStore if data is not found in the LocalStore. Additionally, this updates EdenServer to manage the BackingStore objects. It maintains a map of the BackingStore objects created for each known repository. Reviewed By: bolinfest Differential Revision: D3409602 fbshipit-source-id: 2920dc4c24ee1ec37efb542f058d0d121ceb5532
