[WFLY-456] Log version no matter if we are booting or not
[WFLY-456] Rename audit log type=method to type=jmx
[WFLY-456] Avoid NPE removing syslog appender reference which has not been enabled
[WFLY-456] clean up all audit log queues if no calls were made to enable/disable logging on boot
[WFLY-456] Make sure that audit log log-boot gets set for jmx subsystem
[WFLY-456] Use bootDone() to set whether we are booting or not, and keep that state in ManagedAuditLoggerImpl rather than passing it in
