When an instance has gigabytes of GC log files, the support bundle generator can effectively take forever. This not only causes high load for Jenkins, but can prevent from generating a support bundle.

Steps to reproduce

1. Add 100's GB of log files to the GC folder (specified in JVM startup flags)
2. Try to collect a Bundle

Expected Behavior: The bundle is generated in a reasonable amount of time and just includes the most recent data from the GC logs instead of trying to include all of them.

Actual Behavior: You will see that the bundle collection times out or runs forever.
