I would prefer that resctrl uses as consistent interface as possible
between the different files. There are a few files that already
take domains as input (schemata, mbm_total_bytes_config,
mbm_local_bytes_config) and they all separate domains by ";".
I thus find it most appropriate to stick with ";" between domains.

Regarding separation of groups, in schemata file for example it is
already custom to separate groups (resources in that case) with "\n".
