I am not sure if this is a bug. If you want to use client.py as a library - you should be able to create several instances of Client class.
If you want to use CLI - you get one connection per CLI invocation.
Please specify what do you mean by "create scenarios for benchmarking more than one Fuel node simultaneusly". Do you want to be able to specify which master node you want to connect to with CLI arguments?
