[Feature]: Looking for codemod to be able to convert below examples

### Self-service

- [ ] I'd be willing to implement this feature

### Problem

```
const AWS = require('aws-sdk');

credentials = new AWS.EC2MetadataCredentials()

credentials = new AWS.EnvironmentCredentials('AWS');

credentials = new AWS.SharedIniFileCredentials({...);

const endpoint = new AWS.Endpoint(uri.host);

const req = new AWS.HttpRequest(endpoint);

const signer = new AWS.Signers.V4(req, 'es');
signer.addAuthorization(credentials, new Date());

const send = new AWS.NodeHttpClient();

```

### Solution

The codemode to convert them to V3 https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/migrating-to-v3.html

### Alternatives

N/A

### Additional context

_No response_

Start with the listed AWS SDK v2 examples and the linked AWS SDK for JavaScript v3 migration guide; no files, tests, or entry points are named in the issue. Define the documented v3 conversions for the credential classes, Endpoint, HttpRequest, V4 signer, and NodeHttpClient, then verify the codemod handles those examples.
