Description

When using JpaTransactionManager it "Binds a JPA EntityManager from the specified factory to the thread". Meaning that on top of the EntityManager created for each JpaConsumer, each time it creates a new EntityManager.

New property:
sharedEntityManager - whether to use spring's SharedEntityManager for the consumer/producer. Sets joinTransaction=false

Also added as a property to the JpaComponent.
