Issue description
JPPF uses lot of calls of JPPFConfiguration.getProperties(), JPPFDriver.getInstance() and others. These calls and static fields for mutable JPPF instances should be eliminated. Main reason is to support independent configurations for every JPPFClient instance. Current implenetation initializes some parameters during creating first instance of JPPFClient. So when client is closed and then created with new configuration parameters some stay unchanged from old instance.
