Docker Wildfly - increase Transaction timeout to 15 min

[rsoika]

We need to increase the transaction timeout for officeworkflow from 5 to 15 minutes

    <subsystem xmlns="urn:jboss:domain:transactions:6.0">
        <core-environment node-identifier="${jboss.tx.node.id:1}">
            <process-id>
                <uuid/>
            </process-id>
        </core-environment>
        <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager"/>
        <!-- set transaction timeout from 5min to 15min -->
        <coordinator-environment default-timeout="900" statistics-enabled="${wildfly.transactions.statistics-enabled:${wildfly.statistics-enabled:false}}"/>
        <object-store path="tx-object-store" relative-to="jboss.server.data.dir"/>
    </subsystem>
