Fix FindBugs warnings in sal-clustering-commons

Fixed FindBugs warnings in sal-clustering-commons and enabled the maven plugin to
run and fail the build on violations.

For some reason, the plugin sometimes creates a local .fbExcludeFilterFile that
is a copy of the one in odlparent. It may be that it doesn't always clean it up
at the end. So I added it to the .gitignore
