VertexVertexProperty.Cardinality for that key.
The default cardinality can be vendor defined and is usually tied to the graph schema.
The default implementation of this method determines the cardinality
graph().features().vertex().getCardinality(key). The provided key/values are the properties of the
newly created VertexProperty. These key/values must be provided in an even number where the odd
numbered arguments are String.property in interface VertexV - the type of the value of the vertex propertykey - the key of the vertex propertyvalue - The value of the vertex propertykeyValues - the key/value pairs to turn into vertex property propertiespublic <V> VertexProperty<V> property(VertexProperty.Cardinality cardinality, String key, V value, Object... keyValues)

to the value. If the cardinality is VertexProperty.Cardinality.list, then add a new value to the key.
If the cardinality is VertexProperty.Cardinality.set, then only add a new value if that value doesn't
already exist for the key. If the value already exists for the key, add the provided key value vertex property
