feat(algorithm): support biased second order random walk

[diaohancai]

Purpose of the PR

• implement #279
• follow-up #274 (V1 version)

Main Changes

The current random walk algorithm requires 2 additional features.

1. Biased random walk.
2. Second order random walk.

Add the following parameters:

    private String weightProperty;
    private Double defaultWeight;
    private Double minWeightThreshold;
    private Double maxWeightThreshold;

    private Double returnFactor;
    private Double inOutFactor;

1. String weightProperty. To implement biased random walk. The higher the weight, the higher the probability of walking.
2. Double defaultWeight. Provide a default value if the weight is null.
3. Double minWeightThreshold. Truncate when weight is less than the threshold to avoid too small weight.
4. Double maxWeightThreshold. Truncate when weight exceeds the threshold to avoid overweighting.
5. Double returnFactor. Controls the probability of re-walk to a previously walked vertex.
6. Double inOutFactor. Controls whether to walk inward or outward.

For more details about returnFactor and inOutFactor, please refer to the paper《node2vec: scalable feature learning for networks》.
