[Graph Generation Algorithms] Added Watts-Strogatz Graph and regression tests

[WendelLana]

This new function adds the Watts-Strogatz graph algorithm for Apache AGE. (Project Apache AGE Graph Generation Algorithms)
For more information about Watts-Strogatz see this issue.
Syntax:

ag_catalog.age_create_watts_strogatz_graph(graph_name Name, n int, k int, p float
                                    vertex_label_name Name DEFAULT = NULL,
                                    vertex_properties agtype DEFAULT = NULL,
                                    edge_label_name Name DEAULT = NULL,
                                    edge_properties agtype DEFAULT = NULL,
                                    bidirectional bool DEFAULT = true)

Input:

• graph_name - Name of the graph to be created
• n - The number of nodes
• k - Each node is joined with its k nearest neighbors in a ring topology.
• p -The probability of rewiring each edge
• vertex_label_name - Name of the label to assign each vertex to.
• vertex_properties - Property values to assign each vertex. Default is NULL
• edge_label_name - Name of the label to assign each edge to.
• edge_properties - Property values to assign each edge. Default is NULL
• bidirectional - Bidirectional True or False. Default True.

@WendelLana All new functions need to be added to the file age--1.5.0--y.y.y.sql to allow for upgrading.
