Specifying connection settings in the plugin section

  Sometimes it's necessary to set (or override) the connection settings
  which are needed at build time in the plugin section because the persistence.xml
  doesn't contain the correct information.
  
  This can be performed with the 2 optional parameters
 
  * <<<connectionDriverName>>> which defines the driver class
  
  * <<<connectionProperties>>> which defines further properties
