Core dependency change from @aws-sdk to @smithy

[RanVaknin]

Announcement

Smithy is a language for defining services and SDKs. It is open source software maintained by AWS.
smithy-typescript is used to generate both the AWS SDK for JavaScript v3 and other TypeScript SDKs not necessarily related to AWS. Previously, smithy-typescript generated clients that relied on components vended under the @aws-sdk scope on NPM. We decided to migrate some of those components, including node-http-handler to the @smithyscope to better reflect their generic, non-AWS specific nature. Because they are generic, the migration of these packages is essentially a rename only and code examples and interfaces will continue to work with @smithy packages in the same way their @aws-sdk equivalent worked previously.

As far as discoverability goes, customers will get a warning stating deprecation and now moved:

$ npm i @aws-sdk/node-http-handler
npm WARN deprecated @aws-sdk/node-http-handler@3.374.0: This package has moved to @smithy/node-http-handler
