Subject: Import Koschei Koji plugin


Import an existing, simple simple Koji Hub plugin to base the new work
on instead of starting from scratch.

This is cherry-pick of Koschei commit
bcbd476efecba2d23fcf9b773e11dacdcaabf29c.

+Koschei Koji plugin
+===================
+
+Installation
+------------
+
+First install plugin file in Koji hub file system:
+
+    mkdir -p /usr/lib/koji-hub-plugins/
+    cp koji/plugin.py /usr/lib/koji-hub-plugins/koschei.py
+
+And then enable it in hub config.  `/etc/koji-hub/hub.conf` should
+contain:
+
+    PluginPath = /usr/lib/koji-hub-plugins
+    Plugins = koschei
+
+Since repos created by Koschei plugin don't physically exist on hub,
+appropriate redirect must be added.  Create
+`/etc/httpd/conf.d/koschei-repos.conf` with the following content:
+
+    RewriteEngine on
+    RewriteRule "^/kojifiles/repos/(.*)" "http://master-koji.example.com/kojifiles/repos/$1" [R,L]
+
+Koji hub needs to be restarted for the changes to take effect:
+
+    systemctl restart httpd
+
+Now Koschei Koji plugin should be installed.  To verify that, run
+`koji list-api` command -- it should now display `koscheiCreateRepo`
+as one of available API calls.
+
+Usage
+-----
+
+Example plugin usage from Python:
+
+    import koji
+    ks = koji.ClientSession('http://koji.example.com/kojihub')
+    ks.login()
+    ks.koscheiCreateRepo(582920, 'f24-build')
