rlinks: support wildcard registrations and subscription

[om26er]

Rlinks currently don't support wildcard subscriptions and registrations. I think it's an important missing feature and something we should implement.

@oberstet can you share your thoughts on the implementation design for this one ?

[oberstet]

I haven't thought about this at the code/design level and, fwiw, I would first solve #1903, as otherwise testing will become very hard

Agreed. I will start working on that and will continue the conversation on that issue. Once we have some sort of automation in place, then will come back to this issue

also, there are some existing automated tests which are currently deactivated (because sth with the CI wasn't working):
