[pve-devel] [RFC PATCH manager 4/4] ui: pci mapping: rework mapping panel for better user experience

[Dominik Csapak <d.csapak@proxmox.com>]

by removing the confusing buttons in the toolbar and adding them as
actions in an actioncolumn. There a only relevant actions are visible
and get a more expressive tooltip

with this, we now differentiate between 4 modes of the edit window:
* create a new mapping altogether
  - shows all fields
* edit existing mapping on top level
  - show only 'global' fields (comment+mdev), so no mappings
* add new host mapping
  - shows nodeselector, mapping and mdev, but mdev is disabled
    (informational only)
* edit existing host mapping
  - show selected node (displayfield) mdev and mappings, but only
    mappings are editable

we have to split the nodeselector into two fields, since the disabling
cbind does not pass through to the editconfig (and thus makes the form
invalid if we try that)

this is not intended to be applied as is, rather i'd like some feedback
on the approach (@thomas, @aaron ?) so that if we want to do it this way
i can also do it for the usb mappings

the other approach mentioned off-list can still be done
(having a full grid with all mappings regardless of the node)
maybe only for usb devices (there it makes imho more sense) but then
we'd have two interfaces for the mappings instead of one
