Additional resiliency recommendations

The following additional resiliency policies are not included in this library. Some because they are standard ZIO functionality. They can be applied in combination with rezilience policies.

• Add a cache to speed up response time and provide an alternative in case of failures. rezilience does not provide a cache since it is a specialized topic. A library like scalacache offers ZIO integration via cats-effect interop.

• Add a fallback using ZIO#orElse, a ‘degraded mode’ alternative response when a resource is not available. You usually want to do this as the outermost decorator.
