ensure that latest x.y.3 AS, archives, & runtime test-framework plugins/features are added to the coretests site

[7:30 AM] Pavol Srna: @RobStryker hi Rob, got a minute?
[7:31 AM] Pavol Srna: @RobStryker wondering if the (as, runtime) test-framework can be made available e.g. here: http://download.jboss.org/jbosstools/neon/snapshots/updates/coretests/master/
[7:31 AM] Pavol Srna: what do you think?
[7:34 AM] Pavol Srna: I don't see it in the org.jboss.ide.eclipse.as.test.feature on site, maybe needs a rebuild?

[12:49 PM] Nick Boldt: if you want more test plugins/features in the coretests site... make sure they're part of the server site [1] and then PR me to add them to the coretests site [2].
