bump logging versions; control j.u.logging calls

log4j2 2.1 has a java.util.logging bridge, but it does not work
with the jboss java.util.logging bridge. However, upgrading the
jboss logging version adds direct support for log4j2. The end
result is that things are hopefully easier to configure and maybe
slightly faster.

Specifically, this will hopefully ensure netty logging messages
are printed correctly.
