Add api-resource-locks feature
Added ResourceLockFeatureAPI, to provide an interface for PolicyGuard to use to access other locking mechanisms. Move lock API to policy-core. Changed the interface and added Callback support. Added a class to invoke the API implementers. Changed to set a future instead of expecting the callback to implement the future interface. Also refactored, creating "lock" sub-package. Add junit tests. Increase junit coverage. IsLocked & isLockedBy should check all arguments. Make ImplFuture protected instead of public. Simplify locking - move callback support to an optional feature. Move Reference class to policy-utils. Return plain Future instead of LockRequestFuture. Change-Id: I65154d33833914b4332e02d1ef2512f4c5f09b16 Issue-ID: POLICY-577 Signed-off-by: Jim Hahn <jrh3@att.com>
