LDEV-3318: Move jboss-log4j.xml configuration to jboss logging subsystem in standalone.xml. Apparently there is no way to simultanously use both logging conifgs. All not-commented appenders and loggers from old configuration were migrated.
LDEV-3318: fix jboss-log4j.xml configuration for Wildfly. Change appenders and errorHandlers from 'org.jboss.logging' to 'org.apache.log4j' types. Use 'jboss.server.base.dir' variable as base for logs files location.
