SDK Crate Reorganization Upgrade Guidance

[jdisanti]

The modules in the SDK crates have been reorganized as of this release. If you are using an IDE, the easiest way to upgrade will be to delete all imports from aws_sdk_* and use the IDE features to automatically re-import the types. Otherwise, consider searching the docs on docs.rs to find the new module for any given type that fails to resolve.

Specific changes:

• crate::types -> crate::primitives
• crate::model -> crate::types
• XyzInput, XyzOutput, XyzError => crate::operation::xyz::{XyzInput, XyzOutput, XyzError}, where Xyz is the name of an API (e.g., GetObject in S3)
• Some error types in crate::error have moved to crate::types::error
