Pick and Process pre-defined templates based on parameters to generate gremlin query

Parameters:

traversal - Gremlin Traversal

key - Query Condition Key

value - Query Condition Value

bound - Query Condition Value Range

operator - Query Operator representing conditional operators e.g < , <=, >, >= , =

Returns:

A Gremlin Query Part equivalent to Contraint.
