Add ApiUtils to facilitate looping over features
A number of places in the code (common & drools-pdp) loop over features, giving each provider a chance to act on something. Created a common method in a new ApiUtils class to faciliate it. Renamed to FeatureApiUtils per review comment. Change-Id: I0c2cf0f33854cb5b6921b394f64de498a6234909 Issue-ID: POLICY-1968 Signed-off-by: Jim Hahn <jrh3@att.com>
