Defines a stub cache implementation to be used during installation.
The stub implementation is needed when database access is not yet available. Because Backdrop's caching system never requires that cached data be present, these stub functions can short-circuit the process and sidestep the need for any persistent storage. Using this cache implementation during normal operations would have a negative impact on performance.
