Apply multiplicity Rule upon Edge creation
Uses multiplicity type from dbedge rules json to validate whether to and from vertices meet the multiplicity constraint e.g. ONE2MANY. This validation is applied when creating or updating an edge. Issue-ID: AAI-1197 Change-Id: Id6e78635c5cbea66d8a35e6901b7e1b673125e4e Signed-off-by: michaere <michaere@amdocs.com>
