Fix sonars in clamp

Fixed some sonars:
- no assertion in test case
- unused fields
- unthrown exception
- define a constant
- use boolean instead of Boolean
- remove unused parameter

Fixed some eclipse warnings:
- unused imports
- unused methods
- suppress warnings
- add type parameter

Renamed directory from "org.onap.policy..." to "org/onap/policy/...".
