[teiid-designer-announce] Teiid email list consolidation

We're removing the following email lists which haven't been very active over the years and are basically redundant. * https://lists.jboss.org/mailman/listinfo/teiid-designer-users * https://lists.jboss.org/mailman/listinfo/teiid-designer-announce * https://lists.jboss.org/mailman/listinfo/teiid-designer-dev * https://lists.jboss.org/mailman/listinfo/teiid-announce * https://lists.jboss.org/mailman/listinfo/teiid-dev So moving forward, we'll be using the following as the primary list for TEIID announcements and miscellaneous posts. * https://lists.jboss.org/mailman/listinfo/teiid-users Note that teiid-issues, teiid-commits, teiid-designer-issues and teiid-designer-commits will remain in place since they are integrated with JIRA and GIT.
