Handle Redis connection errors

[aviupadhyayula]

Adds flags to django_redis cache. Handles Redis connection errors silently, and falls back to DB when the cache is inaccessible. [1] Also adds socket timeouts on initial connection and subsequent requests. [2] This enables fast failures when the cache is down, instead of waiting indefinitely.

Verified this works locally by pointing the development cache to an incorrect Redis host, and querying a route that relies on caching.

Unsure how (or if) to add a unit test for this. Would love to hear ideas.
