IMPALA-10073: Create shaded dependency for S3A and aws-java-sdk-bundle
The aws-java-sdk-bundle is one of the largest dependencies in the Impala
Docker images and continues to grow. The jar includes SDKs for
every single AWS service.
This patch removes most of the unnecessary SDKs from the
aws-java-sdk-bundle, thus drastically decreasing the size of the
dependency. The Maven shade plugin is used to do this, and the
implementation is similar to what is currently done for the hive-exec
jar.
This patch takes a conservative approach to removing packages from the
aws-java-sdk-bundle jar, and I ensured no direct dependencies of the S3
SDK were removed. The idea is to only remove dependencies that S3A would
never conceivably need. Given the huge number of AWS services, I only
focused on removing the largest SDKs (the size of each SDK is estimated
by the number of classes in the SDK).
This decreases the size of the Docker images by about 100 MB.
Testing:
* Ran core tests against S3

> One of the largest dependencies in Impala Docker containers is the
> aws-java-sdk-bundle jar. One way to decrease the size of this dependency is
> to apply a similar technique used for the hive-exec shaded jar:
> [https://github.com/apache/impala/blob/master/shaded-deps/pom.xml]
> The aws-java-sdk-bundle contains SDKs for all AWS services, even though
> Impala-S3A only requires a few of the more basic SDKs.
> IMPALA-10028 and HADOOP-17197 both discuss this a bit as well.
