Removed forward of non accepted parameters to transport constructor

[gabypascha]

The transport class does not accept the parameters in its constructor and it is passed in the node_configs instead.

The transport class constructor does not accept the following parameters :

• connections_per_node
• http_compress
• verify_certs

The passing of these parameters causes TypeErrors as the constructor receives unexpected keyword arguments.

These parameters are now passed through the node_configs parameter instead.
