Garbage collect murano package cache

Registered by Kirill Zaitsev on 2016-03-30

Currently engine package cache is optimistic — meaning, that whenever murano-engine downloads a newer version of package it checks if any of the previous versions are in use. If they are — they're left untouched untill the next download operation. This means, that cached packages can stay in cache for very long time. Murano would benefit from having a separate service, that would GC old and unused packages and enforce size constraints on the cache.
