JDK-8232051 - Epsilon should warn about Xms/Xmx/AlwaysPreTouch configuration
Description
For Epsilon, we have added log_warning messages when heap size and AlwaysPreTouch configuration is not great with JDK-8232051. Unfortunately, this means we print this warning all the time, even though users might not actually run into problems there, or when users tried to implement these suggestions and still decided to run against them.

I think we want to emit the suggestions in the normal GC log instead, so they are not printed all the time.
