More sonar fixes in policy/common

Note: this does not increase code coverage, but should fix other
code issues.

Resolved cyclomatic complexity issue in ParameterValidationResult.
Refactored duplicate code in GroupValidationResult.
Removed IOException from NetworkUtil "throws".
Replaced null/empty string tests with StringUtils.isBlank().
Added @FunctionalInterface where needed.
Replaced anonymous classes with lambda expressions.
Replaced duplicate strings with a constant.
Added private constructors for utility classes.
Removed sleep() from tests.
Removed unused parameter from method call.
Made some protected methods private.
Compute integrity monitor's state-transition table once.
Use for-loop instead of iterator.
Moved constructors.
Fixed some checkstyle issues (tabs => spaces, trailing spaces).
