Automatically create related repositories in "modules" when new dist version support is added

[LeonidVas]

When the user adds the tarantool repositories according to instruction, he also adds the "modules" repositories (according to the distribution version of the added repository) as a bonus. When we add support of yet one new distribution version, needs automatically add related repositories to "modules".

Script used for adding repositories.

In fact, we want that such repositories to be created for all supported distribution versions, including old ones(if there are no such repositories yet).

One way to do it: push "noarch" package to new "modules" repos.

And, maybe, initialize old repositories with metadata for new distros. Just for consistency.
