Description of contribution in a few bullet points

• <polygon_name>.max_points parameter was renamed to <polygon_name>.min_points to track its meaning
• Default value for this parameter was adjusted accordingly to not change default CM's behavior
• Old <polygon_name>.max_points is still used (to be removed in the future releases), but now with deprecation warning, if parameter was set by developer
• New testPolygonMaxPoints testcase for max_points deprecated parameter

Description of documentation updates required from your changes
