Updates a cache policy configuration.
When you update a cache policy configuration, all the fields are updated with the values provided in the request. You cannot update some fields independent of others. To update a cache policy configuration:
Use GetCachePolicyConfig to get the current configuration.
Locally modify the fields in the cache policy configuration that you want to update.
Call UpdateCachePolicy by providing the entire cache policy configuration,
including the fields that you modified and those that you didn't.
For .NET Core this operation is only available in asynchronous form. Please refer to UpdateCachePolicyAsync.
