Created a factory for StorageInterface objects
Implemented session storage service factory

- Marshals arguments from Config service
- Proxies to Zend\Session\Storage\Factory for actual creation
Added note about save handler service

- Save handler factory will not be provided by the framework at this
  time.
Created session Container abstract factory

- Provide an array of container names in "session_containers"
  configuration.
- Uses `Zend\Session\ManagerInterface` service, if available, when
  instantiating containers.
- Session container services must be prefixed with "SessionContainer\\"
Fixes typo in docblock
