Description of problem:

yum-plugin-changelog cannot be used with DNF and dnf-plugin-changelog is not available yet.

Version-Release number of selected component (if applicable):

$ dnf --version
1.1.5
  Installed: dnf-0:1.1.5-1.fc23.noarch at 2015-12-30 23:50
  Built    : Fedora Project at 2015-12-18 17:24

  Installed: rpm-0:4.13.0-0.rc1.7.fc23.i686 at 2015-11-24 04:46
  Built    : Fedora Project at 2015-11-20 13:07


How reproducible:

Always, since DNF has been introduced to Fedora.

Steps to Reproduce:
1. dnf search changelog | egrep -i 'yum|dnf'
2.
3.

Actual results:
yum-plugin-changelog.noarch : Yum plugin for viewing package changelogs

Expected results:
yum-plugin-changelog.noarch : Yum plugin for viewing package changelogs
dnf-plugin-changelog.noarch : DNF plugin for viewing package changelogs

Additional info:

https://github.com/rpm-software-management/dnf/blob/master/doc/cli_vs_yum.rst states that yum-plugin-changelog has not been ported to DNF yet. This RFE should change that :-)
