INT-3628: Use SchedulingAwareRunner for Long Tasks

JIRA: https://jira.spring.io/browse/INT-3628

Certain tasks in Spring Integration are long running. Indicate
so for the benefit of platforms such as WebLogic that can log warnings
for long running tasks otherwise.

Also fix conflicting versions of commons-io.
