Address sonar issues in models

Addressed the following sonar issues:
- use RE2 instead of java.util Pattern for "+" and "*"
- don't use deprecated methods
  - for Date(long), sonar appeared not to parse the argument's
    type correctly.  Modified the code slightly to make sonar happy
- duplicate blocks of code
- either log or throw
- missing assert in junit
  - for SDNR & VFC, eliminated threads, as they are unnecessary
- duplicate code block in different branches
- useless assignments
- redeclaring abstract methods
- cyclomatic complexity
  - used lombok in some cases (e.g., EqualsAndHashCode)
- assert argument order
  - actually deleted ControlLoopTargetType, because it is not needed
    and sonar complains regardless of which order is used
- add private constructor to utility classes
- use StandardCharsets instead of literals

Also:
- added logback-test.xml to SO to eliminate the voluminous output
  from the junit test
