Fix sonar issue with double compare4.0.0-ONAP1.4.0

The gson code to convert Double to Long/Integer use a direct comparison
of the original double with a long.  However, sonar does not like that
so changed the code to use the Double.compare() method instead.
Also fixed sonar issue with diamond operator.
Addressed some sonar issues in ServiceManager.
Addressed some sonar issues in Version.
