CACHE_REDIS_HOST broken

[joshgummersall]

TL;DR

The way env prefixing is used in the current repo for cache configuration is broken. CACHE_ is included as a prefix twice for Redis host/port environment variables.

Expected behavior
Services with caching should work with the provided Terraform configuration

Observed behavior
Services with caching do not work.

Reproduction

Deploy from master

The fix should be to either remove the dupe env:", prefix="CACHE_" from the Redis cache config or to remove the prefix everywhere cache.Config is referenced.

The acute fix I used was the change CACHE_REDIS_HOST to CACHE_CACHE_REDIS_HOST in Terraform files.

Dupe of #400. Although that should have been already fixed depending on when you pulled.

[sethvargo]

Fixed in #402. Please ensure you're on that commit or later.

Probably landed just after I pulled and deployed. Thanks!
