[HUDI-5627] Improve the usability of Hudi CLI bundle

[yihua]

Change Logs

This PR improves the usability of Hudi CLI bundle by changing hudi-cli-with-bundle.sh:

• Adds the ability to specify existing hudi-cli-bundle and hudi-spark-bundle jars downloaded by user, through environmental variables CLI_BUNDLE_JAR and SPARK_BUNDLE_JAR. Currently it assumes that these jars are built inside Hudi repo and there is no way to specify the jars from another path.
• Automatically downloads the auxiliary jars to auxlib/ for Hudi CLI. Right now, Hudi CLI bundle still requires additional org.glassfish:jakarta.el and jakarta.el:jakarta.el-api jars in the Java classpath to start the Hudi CLI shell. Auto-downloads make it easier for the users.

Impact

Makes hudi-cli-with-bundle.sh easier to start Hudi CLI shell.

This is tested locally on Spark 3.3. The Hudi CLI shell can start without any problem.

Risk level

low
