Implementation of LoggerContextFactory which acts as the bootstrap for mule's logging mechanism.

It forces ArtifactAwareContextSelector as the only selector, XmlConfigurationFactory as the only available ConfigurationFactory, and sets AsyncLoggerExceptionHandler as the ExceptionHandler for failing async loggers.

Other than that, it's pretty much a copy paste of Log4jContextFactory, due to that classes' lack of extensibility.

By forcing XmlConfigurationFactory as the only available ConfigurationFactory we're disabling log4j2's ability to take json and yaml configurations. This is so because those configuration factories depend on versions of the jackson libraries which would cause conflict with the ones in mule. TODO: Upgrade the jackson libraries bundled with mule so that this restriction can be lifted off

This class also implements ShutdownCallbackRegistry to avoid default behaviour which is
