Code Issues Proposed changes

lazy loading of oslo_cache

Browse Source 
Now, we depend on oslo.cache [1], and use the private/internal
memcache_pool code of the lib, making oslo.cache failing to import
instead of just log an error about missing requirement for selected
drivers at runtime.

This change restores the previous behavior by lazy loading the module.
