richard-churchman 1fcf65eb12 Implemented Redis Resiliency and improved failover capabilities:
* Replaced the StackOverflow Redis client in the Cache library with the Resilient Redis Library.
* Improved policy wrappers by introducing two distinct policies: one for idempotent operations and one for increment operations. Added a circuit breaker to the Redis Resiliency layer to prevent thundering herd on re-instantiation, along with shared state tracking for known-down Redis instances.
* Updated the Redis resilient command wrapper to proxy all commands through the appropriate policy (e.g. based on idempotency).
* Implemented certain other Redis policy state detection.
