* Moving jetty specific pieces out to jetty-webapp-logging so that the
core logging implementation can exist in places such as JVM endorsed
library paths and still function, without bringin in all of Jetty in
the process.
* Removing dependency on any jetty components from
jetty-centralized-logging per reasons above.
* Establishing jetty-webapp-logging as central place to house the webapp
logging integration bits and pieces.
