Bug alert for evict unused items task

[Brian Fox]

We recently discovered that the "Evict unused items task" can potentially evict artifacts from hosted repositories even though it is intended for proxy repositories. If you are using this task, please either disable it or ensure that you have selected a proxy repo or a group that contains only proxy repos in it.

You can follow the jira fix here:  https://issues.sonatype.org/browse/NEXUS-2121 and it will be included in the next release.
