DNF gotta go fast

Dnf is a bit slow by default can these options be added to “/etc/dnf/dnf.conf”

“fastestmirror=True”
“max_parallel_downloads=10”

And this for ex-apt users

“defaultyes=True”

I can’t make this a default without repackaging dnf with this patch, however I will add this to the welcome screen as an option.
