New datasources have idle-timeout-minutes set to 0 in EAP 6

Issue

• Connections from a newly created datasource are not timed-out by JBoss after more than 30 minutes¹ of idle time
• Though no timeout period was specified during creation (in the web console), the following is added to each new datasource² created

<timeout>
    <set-tx-query-timeout>false</set-tx-query-timeout>
    <blocking-timeout-millis>0</blocking-timeout-millis>
    <idle-timeout-minutes>0</idle-timeout-minutes>
    <query-timeout>0</query-timeout>
    <use-try-lock>0</use-try-lock>
    <allocation-retry>0</allocation-retry>
    <allocation-retry-wait-millis>0</allocation-retry-wait-millis>
</timeout>
