If UNLINK is not supported by the Redis server, we should
fall back to DEL. UNLINK was introduced in Redis 4.

This uses UNLINK in Redis 4 to delete sets. This unlinks the key
from the value but actually deletes the value asynchronously.
With large sets this should give us a reasonable performance boost.

This commit also implements multi-key deletes for RepositorySetCache
methods in the Repository model, meaning only one UNLINK call will be
issued for all sets being expired.
