transport: Pass argparse.Namespace directly into transport classes

It's odd that the individual transport driver specifies their argparse
options but then the core transport part evaluates them individually.
This means we cannot add new options within a transport.

Let's pass the Namespace instance into the constructor of the
specific transport to improve this.
