Add support for parameter inheritance
Common parameter support does not allow for inheritance of parameters from a super class. This change allows inheritance of public and protected members from a parameter superclass to a parameter subclass. Issue-ID: POLICY-1222 Change-Id: Ia4f452abab80953b41784c44e4202e8d5405a197 Signed-off-by: liamfallon <liam.fallon@est.tech>
