Increases timeout on sun.misc.GC.requestLatency in
JreMemoryLeakPreventionListener

The JreMemoryLeakPreventionListener causes a full GC every hour when
gcDaemonProtection=true.

The prevention technique invokes sun.misc.GC.requestLatency with a value of
360000.  Increasing the value to Long.MAX_VALUE would be beneficial.

The attached patches add a default setting of Long.MAX_VALUE (add documentation
update), but also permit it to be configured to a lower value using a System
property.
