// Creates a new Amazon File Cache resource. You can use this operation with a
// client request token in the request that Amazon File Cache uses to ensure
// idempotent creation. If a cache with the specified client request token exists
// and the parameters match, CreateFileCache returns the description of the
// existing cache. If a cache with the specified client request token exists and
// the parameters don't match, this call returns IncompatibleParameterError . If a
// file cache with the specified client request token doesn't exist,
// CreateFileCache does the following:
//   - Creates a new, empty Amazon File Cache resourcewith an assigned ID, and an
//     initial lifecycle state of CREATING .
//   - Returns the description of the cache in JSON format.
//
// The CreateFileCache call returns while the cache's lifecycle state is still
// CREATING . You can check the cache creation status by calling the
// DescribeFileCaches (https://docs.aws.amazon.com/fsx/latest/APIReference/API_DescribeFileCaches.html)
// operation, which returns the cache state along with other information.

	// risk of creating an extra cache. This approach can be useful when an initial
	// call fails in a way that makes it unclear whether a cache was created. Examples
