Review comment:
I checked this behavior on a kerberized environment. Here is the folder
structure on a node _without_ Metron services:
```
[root@metron-1 ~]# cd /usr/metron/0.7.0/
[root@metron-1 0.7.0]# ll
total 4
-rwxr-xr-x. 1 metron metron 688 Dec 21 10:18 client_jaas.conf
```
Restarting Metron Client service is still failing with this error:
```
raise Fail("Applying %s failed, parent directory %s doesn't exist" %
(self.resource, dirname))
resource_management.core.exceptions.Fail: Applying
File['/usr/metron/0.7.0/config/zookeeper/../metron_knox_installed'] failed,
parent directory /usr/metron/0.7.0/config/zookeeper/.. doesn't exist
```
The `config/zookeeper` within `$METRON_HOME` needs to be created before we
write the flag file.
