Group parametrized foo@.service services
Typical examples for those groups services:
Those services use "@" as a parameter that ends up in a generated service name and further might be used inside the service to be handles by an %i argument. Currently, these generated services clutter the services list.
Possible solutions:
- group them into one entry
- add an additional level for fine-grained filtering
Since the use case of the service filter is to just provide a coarse filtering, probably it is enough to just group them.
