[pve-devel] [PATCH manager v3 02/13] PVE/API2/Cluster: add Hardware mapping list api call

[Dominik Csapak]

this is a cluster wide api call that returns the list of mappings
in a manner that is easy to consume by the ui (as a tree)

it also automatically includes the validity of mappings on the node
where it is called.

for a consumer of this api call to get a complete picture, it is
necessary to do an api call for each node
