Fix global storage states.

- A storage is not operational while connecting to the primary master
- A storage is not ready until connected to a primary master, with an
operational partition table and fully initialized. The 'ready' attribute
must be initialized to False when PrimaryFailure or OperationFailure
exceptions are reaised to prevent acceptation of incoming clients (see
storage/handlers/identification.py that check app.ready value)
