  Guarantees after this transformation:
  * Within a given nvset, there is at most one nvpair with a given name. If there
    were duplicates prior to this transformation, only the first one is kept.
  * There are no ping nodes. If a node was a ping node prior to this
    transformation, it is now a member (cluster) node with all resources banned
    and probes disabled.
  * There are no legacy promotable clone resources. If a resource was a legacy
    promotable clone prior to this transformation, it is now a standard
    promotable clone (that is, a clone with the meta-attribute "promotable" set
    to "true").
  * There is at most one top-level rule within a location constraint. If a
    location constraint had N top-level rules (N > 1) prior to this
    transformation, it is now converted to N location constraints, each with a
    single top-level rule.
 
  Anything that matches all resource types should be placed in a later
  transformation, so that it can ignore the possibility of legacy promotable
  clone resources.
