We were not closing repositories on Node shutdown. In production, this has little effect but in tests shutting down a node using `MockRepository` and is currently stuck in a simulated blocked-IO situation will only unblock when the node's threadpool is interrupted. This might in some edge cases (many snapshot threads and some CI slowness) result in the execution taking longer than 5s to release all the shard stores and thus we fail the assertion about unreleased shard stores in the internal test cluster. Regardless of tests, I think we should close repositories and release resources associated with them when closing a node and not just when removing a repository from the CS with running nodes as this behavior is really unexpected. Fixes elastic#47689
