Add superclasses for gson-jackson migration
Added common classes needed by other gson-jackson code. Modified some logic to make it more maintainable or perform better. Updated comments and spacing. Fix another comment. Moved gson classes from utils to a separate gson project. Added GsonXxx annotations to mirror jackson annotations. Removed unneeded dependencies from gson pom. Removed old GsonMessage class from policy-endpoints. Removed trailing spaces. Updated licenses. Removed more trailing spaces. Removed unneeded checkstyle suppression file from utils. Change-Id: I1a285500faeb0a0b6a1467d09b92ecd3cded713e Issue-ID: POLICY-1428 Signed-off-by: Jim Hahn <jrh3@att.com>
