Add a new abstraction layer UnifiedOnDiskCache that adds new functions of disk space management and data validation that builds on top of OnDiskGraphDB and OnDiskKeyValueDB. Build upon UnifiedOnDiskCache, it is OnDiskCAS that implements ObjectStore and ActionCache interface for LLVM tools to interact with CAS storage.
