GenericJMSRA would benefit from separately configurable loggers

The present GenericJMSRA implementation uses a single java.util.logging.Logger, identified by its name "com.sun.genericjmsra", for all logging purposes.

(NB This is true even when the resource adapter is deployed multiple times within a single application server, which apparently was never intended but which otherwise works just fine on GlassFish 2 and 3.)

It would be desirable to create multiple (child) loggers so that each Admin Object (for outbound queues/topics) or ActivationSpec (for inbound ones) could have its own log level setting and so that log entries originating with different queues/topics could be correlated with separate logger names. The current situation results in confusing and less-than-truly-helpful server logs in real-world situations when multiple inbound and outbound queues are involved and the (global) log level is cranked up for troubleshooting.
