Subject: [PATCH] Added adapter-cache-redis package

refs https://github.com/TryGhost/Toolbox/issues/515

- Redis-based caches can be used on hosted-environments to store information with high memory impact - when in-memory caches would be too impractical to use
- This is a placeholder package for a cluster-aware Redis cache implementation compatible with Ghost's cache adapter interface (https://github.com/TryGhost/SDK/tree/a41d351f16cb2b934ce755f4464706c01d2078d8/packages/adapter-base-cache)
