+Enhancement: add named locks and refactor cache
+
+Tags: ocis-pkg, accounts
+
+We had the case that we needed kind of a named locking mechanism which enables us to lock only under certain conditions.
+It's used in the indexer package where we do not need to lock everything, instead just lock the requested parts and differentiate between reads and writes.
+
+This made it possible to entirely remove locks from the accounts service and move them to the ocis-pkg indexer.
+Another part of this refactor was to make the cache atomic and write tests for it.
