Automatically determine fedora-all, fedora-stable and fedora-development aliases

Right now, the aliases for fedora-all, fedora-stable and fedora-development are hard-coded in packit/config/aliases.py

It would be better if this was replaced by a query to the public Bodhi REST API to get the current list of stable and development branches. For example (stable releases):

curl "https://bodhi.fedoraproject.org/releases/?exclude_archived=true&state=current" |json_reformat
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  7903  100  7903    0     0  14214      0 --:--:-- --:--:-- --:--:-- 14239

    ],

}

(The results should be restricted to those with the id_prefix of FEDORA).

@ffoto1620 No, it is a stop-gap measure that just updates the aliases to the current stable releases.

Here is a conclusion what needs to be done:

• Get the info about current stable/all/development versions via Bodhi REST API or via bodhi Python client.
• Use hardcoded values if Bodhi is not available.
• When used in Copr, check that the values are present in Copr. (You can use or get inspired by available_chroots method implemented last week by @mfocko )
