The apoc.vectordb.*.get/query procedures should search for nodes/relationships with mapping config

[vga91]

For example the following procedure should return for a node (:Test {myId: '<metadata foo result returned by qdrant API>'}):

CALL apoc.vectordb.qdrant.query($hostOrKey, 'test_collection',
    [0.2, 0.1, 0.9, 0.7],
    {},
    5, 
    { mapping: {
            nodeLabel: "Test", 
            entityKey: "myId", 
            metadataKey: "foo" 
        }
    })
