Adding common utility classes to policy/common

* Adding HealthCheckReport class to policy/common for wider use
  among all policy modules.
* Adding utility class called ParameterValidationUtils for providing
  common validation methods to all policy modules. For now, it has only 3
  validation methods but we all can add more in future.
