Maven repository: MaReTe violations (regression from 7.1.1)

There is a couple [1] of failing MaReTe (maven repository validator) checks which were not present in 7.1.1. It seems there are some extra files, such as:

org/jbpm/jbpm-event-emitters/7.14.0.Final-redhat-00001.pom.1
org/jbpm/jbpm-event-emitters/7.14.0.Final-redhat-00001.pom.md5.1
org/jbpm/jbpm-event-emitters/7.14.0.Final-redhat-00001.pom.sha1.1

In addition, there are non-productized artifacts which were not present in the previous build of the repository ZIP for CR1 [2].
