Java-SDK artifact deployment strategies

[jason810496]

Why

How should user deploy their JARs?
We should know the full user-story ourself.

What

Add ADRs.

I just realized that user could also setup S3 Dag Bundle to pull the JARs to somewhere (if possible, need double check), then setup the coordinator jars_root properly if they insist in deploying with DagBundle.

Another approach pointed out by TP in #65958 (comment).

User might compile all the Java Dag as one Jar and point the main_class to the "single big JAR bundle" that contain all the potential Dags.
