Added the default Jetty, Jersey, and Spring Framework Log4J settings out of the DefaultLogConfigurator and into the log4j.properties files.
Flattened the LoggingService architecture to clean up all of the unused items for swapping out Log4J as the backing log mechanism.
Removed all of the log4j dependencies from the POM's and added the slf4j-log4j12 as part of the Valve POM and also Repose-Aggregator's Test scope.
After flattening the LoggingService architecture, the DefaultConfigurator was able to be removed also.
Valve's ProxyApp was updated to check for and load the log4j.properties in the configuration directory if present.
Removed the reflection call from the LoggingServiceImpl as per team comments.
Added the slf4j-log4j12 dependency to the Core-Lib POM since the reflection call was removed.
Added the slf4j-log4j12 dependency to the Web-Application POM's Package scope to account for the one in Valve not being present.
Updated the test runners in the Installation module for the DEB and RPM suites to be more abstracted and in turn maintainable.
Forgot to add the abstracted/extracted scripts.
Added an explicit dependency on Log4J instead of depending on the transitive dependency of the slf4j-log4j12 binding.
Added the explicit dependency on Log4J instead of depending on the transitive dependency of the slf4j-log4j12 binding to the packaging projects as well.
