Support non-alphanumeric characters in key, value

[lotusnow]

My problem is that my etcd cluster has many '/' character in key names.
etcdmanager seems support only alphanumeric character in key and value.
Please considering support non-alphanumeric characters in key & value

Thank you for your suggestion. Yes, you are probably right about this :). We should definitely support all the characters ETCD supports. We will look into this and will make changes in the next release.
