AFM to cloud object storage operation modes

AFM to cloud object storage filesets and objects have different operation modes.

AFM to cloud object storage operations are serviced either synchronously or asynchronously. Reads and revalidations are synchronous operations, and update operations from an AFM to cloud object storage fileset are asynchronous to a cloud object storage depending upon the afmAsyncDelay interval. All update operations from the writable AFM to cloud object storage filesets such as IW or SW mode are on the primary gateway. Queues on the primary gateway are pushed to the cloud object storage asynchronously based on the afmAsyncDelay interval.
