Use short names as much as possible to reach internal services
### Summary
As explained in https://gitlab.com/sylva-projects/sylva-core/-/merge_requests/6906, since nearly all pods have `ndots:5 config` in their resolv.conf, we should probably try to avoid using long service names everywhere in sylva to avoid failures when resolvers are trying to test domains from the search directive (or use global names finishing with a dot to instruct resolvers to bypass the search directive)
There are many places where we use long names for services:
