Lee Hinman 94625d74e4 No longer allow cluster name in data path
In 5.x we allowed this with a deprecation warning. This removes the code
added for that deprecation, requiring the cluster name to not be in the
data path.

=== Cluster changes
==== Cluster name no longer allowed in path.data
Previously the cluster name could be used in the `path.data` setting with a
warning. This is now no longer allowed. For instance, in the previous version
this was valid:
[source,sh]
--------------------------------------------------
# Assuming path.data is /tmp/mydata
# No longer supported:
$ tree /tmp/mydata
/tmp/mydata
├── <cluster_name>
│   └── nodes
│   └── 0
│   └── <etc>
# Should be changed to:
$ tree /tmp/mydata
/tmp/mydata
├── nodes
│   └── 0
│   └── <etc>
--------------------------------------------------
