An etcd cluster is not necessarily only dedicated to seaweedfs. This security enhancement adds a customizable key_prefix option to the etcd filer store. This will allow an etcd cluster administrator to limit the seaweedfs etcd user to only read/write a subset of keys under the key_prefix, instead of all keys on the etcd cluster.
