Feature request: Include SSD read and write IOPS date for local SSD instances

For instance types with local SSD, the DB does not contain the read and write IOPS values. 

AWS publishes these values for all recent instance types, e.g., here for the storage optimized types:

https://docs.aws.amazon.com/ec2/latest/instancetypes/so.html#so_instance-store

I'm not sure if they are available through the API though.
