support for ODL format and specifying a Logger by name

[ilfur]

This is more of an enhancement request than a problem... there is a need to support Logging for components on top of WebLogic, like Service Bus, Analytics Publisher and more. Instead of using the default WebLogic Logger, one must be able to specify the Logger by name, like "oracle.osb". The ODL format is different from standard WebLogic logging, almost like JSON with brackets around most of the items: [timestamp] [component id] [messagetype:level] [message-id] [module id] ([field-name: field-value])* message-text [supplemental-detail]
