Retired dnf-langpacks in rawhide

[Parag Nemade]

Hi,
   Last release we implemented[1] new way of installing langpacks
packages using RPM's weak dependency feature. Therefore, I would like
to retire dnf langpacks plugin package called dnf-langpacks in
rawhide(f25+).

   Those who still want to know what is current way of installing
language packages please check this test case page[2].

   I have also submitted a pull request for fedora-comps to remove
dnf-langpacks package from "standard" as well as
"workstation-product"
group.

Thanks.
Parag.
