// Creates a snapshot of an existing Amazon FSx for OpenZFS volume. With
// snapshots, you can easily undo file changes and compare file versions by
// restoring the volume to a previous version. If a snapshot with the specified
// client request token exists, and the parameters match, this operation returns
// the description of the existing snapshot. If a snapshot with the specified
// client request token exists, and the parameters don't match, this operation
// returns IncompatibleParameterError . If a snapshot with the specified client
// request token doesn't exist, CreateSnapshot does the following:
//   - Creates a new OpenZFS snapshot with an assigned ID, and an initial
//     lifecycle state of CREATING .
//   - Returns the description of the snapshot.
//
// By using the idempotent operation, you can retry a CreateSnapshot operation
// without the risk of creating an extra snapshot. This approach can be useful when
// an initial call fails in a way that makes it unclear whether a snapshot was
// created. If you use the same client request token and the initial call created a
// snapshot, the operation returns a successful result because all the parameters
// are the same. The CreateSnapshot operation returns while the snapshot's
// lifecycle state is still CREATING . You can check the snapshot creation status
// by calling the DescribeSnapshots (https://docs.aws.amazon.com/fsx/latest/APIReference/API_DescribeSnapshots.html)
// operation, which returns the snapshot state along with other information.
