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

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.

Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:

  • Best of breed performance and scalability.
  • Support for data stored in HDFS, Apache HBase, Apache Kudu, Amazon S3, Azure Data Lake Storage, Apache Hadoop Ozone and more!
  • Wide analytic SQL support, including window functions and subqueries.
  • On-the-fly code generation using LLVM to generate lightning-fast code tailored specifically to each individual query.
  • Support for the most commonly-used Hadoop file formats, including Apache Parquet and Apache ORC.
  • Support for industry-standard security protocols, including Kerberos, LDAP and TLS.
  • Apache-licensed, 100% open source.
