Remove cache circuit breaker

[chr15stevens]

Description

Removed circuit breaker from http-transport-cache.

Motivation and Context

The cache circuit breaker was doing very little to protect caches in the case of the recommended catbox-redis and redisio cache libraries. We decided to remove this and consumers of this library should implement their own circuit breaker if necessary.
