Allow selecting all queues with sidekiq-cluster
What does this MR do?
Because it was designed for selecting specific queues, sidekiq-cluster didn't have a convenient method to select all queues. As we want this to become the default sidekiq entry point for all GitLab installations, and the default is to handle all queues in a single process, we need that option.
(This was possible before: using
could ask for something like
that's not obvious.)
Instead of making
* a wildcard anywhere, which would be more general,
this commit just allows a single
* in a queue group to represent all
queues. While this is less general, it's also simpler to implement, and
we can assume that YAGNI for the wildcards.
