Fix simple sonar issues in models: errors to sim-pdp

models-errors
models-pdp
models-provider
models-sim-pdp

Also had to work around this checkstyle issue:

src/test/java/org/onap/policy/models/sim/pdp/comm/
	TestPdpStateChangeListener.java:[77,32] (javadoc) JavadocMethod:
	Unable to get class information for @throws tag
	'PdpSimulatorException'.

The error appears to be bogus, as PdpSimulatorException is on the
"throws" line thus indicating that the class IS accessible to the
above java file.
