RPC: PoolService::UnlinkRepositoryFromPool
This removes the connections between a participant repository and its former pool repository. This is a risky operation. If the participant repository still relies on objects in the pool repository, it will become corrupt after this RPC call. This call finalizes PoolService::PrepareLeavePool.
Also see worked example in https://gitlab.com/gitlab-org/gitaly/blob/jv-explore-dedup/test-dedup.
