Improvements to Parameter Srvice
Add proper handling for optional parameters Add setName() to the parameter group interface to force definition of that method Add some convenience metnods to parameter service Issue-ID: POLICY-1035 Change-Id: Iaa9226f45215b00aff9b78ab5fc120c24a0af46d Signed-off-by: liamfallon <liam.fallon@ericsson.com>
