/**
* DetachVolume action
*
* Detaches an Amazon EBS volume from an instance. Make sure to unmount any file systems on the
* device within your operating system before detaching the volume. Failure to do so will result in volume
* being stuck in "busy" state while detaching.
*
* Note! If an Amazon EBS volume is the root device of an instance, it cannot be detached while the
* instance is in the "running" state. To detach the root volume, stop the instance first.
* If the root volume is detached from an instance with an AWS Marketplace product code, then
* the AWS Marketplace product codes from that volume are no longer associated with the instance.
*
* @param string $volumeId The ID of the EBS volume.
* @param string $instanceId optional The ID of the Instance.
* @param string $device optional The device name.
* @param bool $force optional Forces detachment if the previous detachment attempt did
* not occur cleanly (logging into an instance, unmounting
* the volume, and detaching normally). This option can lead
* to data loss or a corrupted file system. Use this option only
* as a last resort to detach a volume from a failed instance.
* The instance won't have an opportunity to flush file system
* caches or file system metadata. If you use this option, you
* must perform file system check and repair procedures.
* @return AttachmentSetResponseData Returns AttachmentSetResponseData on success
* @throws ClientException
* @throws Ec2Exception
