Feature/zookeeper client security

- [x] Add Client support to `jaas.conf.erb` template
- [x] Move `jaas.conf` from `zookeeper_server` to `zookeeper` recipe
- [x] Add `jaas.conf` to `hbase` recipe
- [x] Add `jaas.conf` to `hive_server2` recipe
it'd be better to validate that these fields exist if usekeytab is true
