I tested things out, and while YETUS-297[1] is present the default runs all
plugins that can do multiple jdks against those available (jdk7 and jdk8 in
our case).

We can configure things to only do a single run of unit tests. They'll be
against jdk7, since that is our default jdk. That fine by everyone? It'll
save ~1.5 hours on any build that hits hbase-server.
