[ISPN-4645] Many XSD default values do not match the defaults from the

corresponding configuration builder

https://issues.jboss.org/browse/ISPN-4645

Updated *ConfigurationBuilder and XSD files to have the correct default
values
Modified test case code that verifies the default value for L1
configuration
OK, @danberindei  just so I have this straight, and we don't go around in circles again!:

1) The default in the XSD for queue-size should be 0
2) The docs in the XSD for queue-size should be updated
3) The default in the code will remain at 1000, because asyn has to be enabled for the queue to be used

Is that correct?
