Marcin Maliszkiewicz 3c1e1f867d raft: auth: add semaphore to auth_cache::load_all ...

Auth cache loading at startup is racing between
auth service and raft code and it doesn't support
concurrency causing it to crash.

We can't easily remove any of the places as during
raft recovery snapshot is not loaded and it relies
on loading cache via auth service. Therefore we add
semaphore.

Closes scylladb/scylladb#27573
