(PR will possibly be shared with the Integration chapter later)

This is a full modularization of the persistence and transaction chapter. I also had some questions; I appreciate we might not resolve all of them quickly. Here they are:

To change the JTA transaction manager do I need to change the code, the persistence.xml file, or some combination?

How to execute the org.jbpm.persistence.jta.ContainerManagedTransactionDisposeCommand in code for CTA transactions? Would need a small sample here to match the other samples in the doc

The configuration section for persistence mentions that the kie-test-util module is provided by ”drools”, which is not a term we use in product docs. Can we just say the product provides this module?

Does the RHPAM installer provide all artifacts for the IDE like the jBPM installer allegedly does?

The doc mentions pointing the jBPM Eclipse plugin to a downloaded “jBPM artifacts”. I used the maven-repository downloadable as a product equivalent but is it really usable in that way? We actually need to provide setting up that plugin as a proper procedure but not right now

The part of the persistence doc about configuring the runtime manager just seems disjointed and I could not reconstruct the process. For example, when a session is restored it is not attached to the runtime manager, so it is unclear how to use it with the runtime manager.
