[releng] Issue #7520: Provide stable names for images

[Till Maas]

till reported a new issue against the project: `releng` that you are following:
``
The images at
https://kojipkgs.fedoraproject.org/pub/fedora/linux/development/rawhide/C...

contain dynamic information in their name that might change daily, e.g.:

Fedora-Cloud-Base-Rawhide-20180525.n.0.x86_64.qcow2 

It would be great if there was also a symlink with a stable name, e.g.
Fedora-Cloud-Base-Rawhide-x86_64.qcow2 to make it easier to automatically download the
latest image. CentOS does this for example as well:
https://cloud.centos.org/centos/6/images/

So, we avoid symlinks because some mirrors are not able to use/mirror them. 

We could hardlink, but then anyone who didn't use hardlinks would get lots of extra
space used. 

I wonder if we couldn't add something to mirrormanager for this case? @adrian what do
you think?

Or, could you just use @adamwill 's fedfind tool?

@till What is the use case here?

One of the use case we heard is:

> <fidencio> mboddu: hey/ping! I'm wondering whether would be
> possible that we could have a fixed symlink pointing to every new rawhide iso. Currently
> we have
> http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Server/x... and
> then the iso names as Fedora-Server-dvd-x86_64-Rawhide-20180530.n.0.iso (for instance).
> Would be possible to have a symlink like Fedora-Server-dvd-x86_64-Rawhide-latest.iso
> pointing to the latest built ISO
>  
<fidencio> mboddu: the reasoning behind that is: we've got some reports
of people who'd like to give it a try on latest rawhide using Boxes (which can
automatically download and express-install the iso for you)

Let me complement this comment.

Boxes gets the URL from osinfo-db in the following format:
https://gitlab.com/libosinfo/osinfo-db/blob/master/data/os/fedoraproject....

As the rawhide ISOs have their URL changing on every new ISO, it makes impossible to
provide a Rawhide experience of "Download and Install this ISO" as we can do for
released ones.

So, that's the main reason we'd benefit from a "latest" link,

I would like to use the images easily for a CI tool to test software against it. It uses a
format that is desscribed here:
https://github.com/linux-system-roles/test-harness/blob/master/README.md

A solution with some mirror manager magic would be great, too. In general it would be
great if mirror manager would only contain redirects for the actual files that are
mirrored and not the directories (I believe I filed this, too, somewhere) then it would be
easy to also provide a virtual link (download.fedoraproject.org is backed by mirror
manager, is it not?)

Btw. since CentOS does it, maybe we can use their solution? Not sure how they actually do
it. Also about the lots of extra space used, the images are rather small (at least the
cloud images, therefore it would not be that much extra space).

@mohanboddu needs to find out if CentOS has mirroring or not. If yes, then can find out
what their solution is. If not, we need to come up with a solution.
