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.

Fixes https://github.com/scylladb/scylladb/issues/27540

4df6b51ac2 auth: fix cache::prune_all roles iteration
During b9199e8b24
reivew it was suggested to use standard for loop
but when erasing element it causes increment on
invalid iterator, as role could have been erased
before.

This change brings back original code.

bd7c87731b auth: add unified cache implementation
It combines data from all underlying auth tables.
Supports gentle full load and per role reloads.
Loading is done on shard 0 and then deep copies data
to all shards.
