* [dynamodb] Update AWS SDK to 2.17.102

- Added NOTICE with all compiled dependencies. Dependencies listed in
  feature.xml are omitted.
- jackson dependency is now provided by AWS SDK as a 'shaded' copy
- log4j version used in tests updated
- Specifying DefaultsMode=STANDARD to make the SDK utilize latest
  recommended parameters. RetryMode is also controlled by DefaultsMode,
  so we avoid setting it explicitly unless overridden by the user.
- Fixed test regressions due to SDK changes

 ### Updating Amazon SDK
 
-1. Clean `lib/*`
-2. Update SDK version in `scripts/fetch_sdk_pom.xml`. You can use the [maven online repository browser](https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-dynamodb) to find the latest version available online.

+1. Update SDK version and `netty-nio-client` version in `scripts/fetch_sdk_pom.xml`. You can use the [maven online repository browser](https://mvnrepository.com/artifact/software.amazon.awssdk/dynamodb-enhanced) to find the latest version available online.
+2. `scripts/fetch_sdk.sh`
+3. Copy printed dependencies to `pom.xml`. If necessary, adjust feature.xml, bnd.importpackage and dep.noembedding as well (probably rarely needed but [it happens](https://aws.amazon.com/blogs/developer/the-aws-sdk-for-java-2-17-removes-its-external-dependency-on-jackson/)).
+4. Check & update `NOTICE` file with all the updated, new and removed dependencies.
 
 After these changes, it's good practice to run integration tests (against live AWS DynamoDB) in `org.openhab.persistence.dynamodb.test` bundle.
 See README.md in the test bundle for more information how to execute the tests.
