The code we had for adjusting the netutils urlsplit
function to add in a params method/property is no
longer needed as that functionality is now pushed into
the oslo.utils repo/package where it can be maintained
there in a more proper manner instead; so we can now
remove our adjustment code and just use the upstream
code instead.
