Description of contribution in a few bullet points

• I added min_laser_range parameter to limit the minimum range being used by the SLAM to create the map similar to max_laser_range parameter
• I add short description in the README.MD about the new parameter
• I add the parameter to all of the sample config file with value of 0 that will trigger the use of laser scan message minimum range

Description of documentation updates required from your changes

• Added new parameter, so need to add that to default configs and documentation page (I have done it in the README part)

Future work that may be required in bullet points
