TMDM-7598: "Reuse settings for connection pool using implementations value for best OOTB experience"

Amend settings specified in TMDM-7598 with: a timeout of 10 minutes (should be way enough in most cases) and specifies a idle check time multiple of timeout time (thanks to Synotis for reporting this).
