Maven repo: suspicious files present

Description of problem:
The Maven repo contains a great number of suspicious files. For example zips, wars or XSDs.

This issue is related to https://bugzilla.redhat.com/show_bug.cgi?id=1056184 but is more general, it lists more that just zip and war files.

See https://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/brms-maven-repo-wolf-validator/lastCompletedBuild/testReport/(root)/SuspiciousFileException/
for up-to-date list of the suspicious files.

Some of the reported issues may be false positives, but IMO at least the war files and some of the zip files should be removed.

Version-Release number of selected component (if applicable):
