Customers are unable to specify specific datasource configuration parameters.

Here's a specific use case to outline why this is necessary:

• kie-server setup with Oracle for jBPM and EJB timers
• running a process instance with a timer hangs
  until it fails at transaction timeout
• To fix this, the following datasource configuration needs to be applied

            <xa-pool>
                <is-same-rm-override>false</is-same-rm-override>
            </xa-pool>
