[pve-devel] [RFC cluster/manager/storage 0/4] add storage mapping support

[Mira Limbeck]

This RFC is the first draft of storage mapping support. It
includes a reworked iSCSI plugin that handles storage mapping, as well
as an API to get/create/delete mappings.

Some features are not yet implemented, for example reachability checks
for iSCSI.
The pve-manager patches are limited to the API, no UI exists for now.

The idea would be to make it easy for iSCSI storages to use local
mappings that are managed through the GUI.
For this we would need to check the reachability of all announced
portals for each node.
This will be the next step after the basic mapping support.

For now only an iSCSI plugin exists, but this could be extended to other
(future) storages as well. As such the idea is to have a generic base.
