EFS FileSystem should support one-zone storage class
https://aws.amazon.com/blogs/storage/lower-your-amazon-efs-costs-by-47-with-one-zone-storage-classes/

This is done by setting the AWS::EFS::FileSystem AvailabilityZoneName
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-efs-filesystem.html#cfn-efs-filesystem-availabilityzonename

Use Case

It's cheaper

Proposed Solution

Expose oneZone property and have that set AvailabilityZoneName to one of the subnet availabilityZones for the subnets the FileSystem is in?
