Description of problem: It happen that several users used copr-fe-dev instance and thought that it is production one. We should be able to define banner on front page, which allow to put there custom text. I would guess that if file /var/lib/copr/banner-include.html exist, we will include it at the top of front page.
Done, runs at copr-fe-dev.
Should be in production now.
