Implement per-service cache

[jefmoura]

Proposal

Buildly Core needs to have its extension of UpdateCacheMiddleware and FetchFromCacheMiddleware, so we can separate the caching data by service. So, Buildly Core will perform a per-service cache. We'll have the following required settings:

• CACHE_MIDDLEWARE_SERVICE_ALIAS – The cache alias to use for storage.
• CACHE_MIDDLEWARE_SERVICE_SECONDS – The number of seconds each service data should be cached.
• CACHE_MIDDLEWARE_SERVICE_KEY_PREFIX – If the cache is shared across multiple applications, set this to the name of the main application.

Developers should also have the option to not use per-service caching.
