Description:
The NodeHandler class is intended for generating and maintaining large numbers of Jenkins

Note:
Need a method to compare current csv with existing nodes and do: Create / Updated / Delete accordingly
Need means for auto launch jenkins node on slave host (server) after (device) nodes are created
