Subject: [PATCH] reclass.storage.node: Merge duplicate nodes

Reclass does not support duplicate nodes in top pillar, so merge all
nodes with the same name into a single node, inheriting classes from
all instances.

This allows using multiple "system.reclass.storage.system.*_cluster"
classes for the same node, based on re-using the name (hostname).

NOTE: defaults.merge module does not merge lists (e.g. for classes),
so handle that case separately.
