Issue Type: Bug

Affects Versions: 2.9.0
Reporter: Alexey Serba
Fix For: 2.9.1
I just recently upgraded my project to 2.9.0 and noticed that
{{PathChildrenCache}} recipe started failing with
{noformat}
Caused by: org.apache.zookeeper.KeeperException$NoNodeException:
KeeperErrorCode = NoNode for /parent

{noformat}
It turns out that {{PathChildrenCache}} recently started using new
implementation {{createContainers}} for creating parent directories/znodes and
this method has a bug in {{NamespaceFacade.createContainers}} implementation,
because it does not account for namespace name.
I'll create a PR with a test and fix shortly.
