Andrzej Jackowski 35fd603acd test: wait for read_barrier in wait_until_driver_service_level_created ...

Previously, `wait_until_driver_service_level_created` only waited for
the `driver` service level to appear in the output of
`LIST ALL SERVICE_LEVELS`. However, the fact that one node lists
`sl:driver` does not necessarily mean that all other nodes can see
it yet. This caused sporadic test failures, especially in DEBUG builds.

To prevent these failures, this change adds an extra wait for
a `raft/read_barrier` after the `driver` service level first appears.
This ensures the service level is globally visible across the cluster.

Fixes: scylladb/scylladb#27019
