this series aims to add a cluster-wide device mapping for pci and usb devices.
so that an admin can configure a device to be availble for migration and
configuring for uses that are non-root

built-in are some additional safety checks in contrast to current
passthrough, e.g. if pci addresses shift, with the mapping
we can detect that and prevent a vm to boot with the wrong device
(in most cases, there are some edge cases when one has multiple
of the same device, e.g. the same gpu, that we cannot detect)

a few pain points that are probably worth discussing/thinking about:
(i did not really get feedback on my last RFC on this)
* the config format
    i changed to a json backed config, since it makes handling it much
    easier (since we have a id -> nodenames -> mapping relation that
    we cannot easily represent with a section config). some
    (small) parts are written from scratch (update/createSchema for
    instance) but we would have to do that anyway

    if wanted i can make the section config work, but it makes the
    handling quite a big uglier (for example, we have name the usb/pci
    properties differently because the section config cannnot have
    different formats for different sections)

* getting the cluster wide info
    the configuring of mappings is all done via node specific api paths,
    but i created a cluster wide api path that returns the overall
    structure for easy consumption from the gui. to get the remaining
    data from the other nodes, i let the gui make an api call
    for each node.

    alternatively we could distribute the necessary info via pmxcfs,
    but we'd have to broadcast basically the whole pci listing for all
    nodes in a relatively short interval, only for it to be extremly
    seldomly used (when looking at the cluster wide hardware
    mappings...)

* some minor things that can be improved are how the gui looks/behaves:
    - 'add new' and 'add mapping' are probably to similar, but i did
      not come up with really better alternatives
    - i find the tree of entry -> node-mappings nice, but there may be
      an even better representation?
    - position in cluster menu is probably not optimal
      (but where to put it?)

changes from the rfc:
* new cluster wide gui instead of node-local one (removed that, since
  it's not necessary when we have a cluster-wide one)
* uses json instead of a section config
* api is quite different overall, i split the type into its own level
  for configuring, similar to what we do in pbs
  (e.g. /nodes/NODENAME/hardware/mapping/usb/)
* fixed quite some bugs the rfc had
* added patch for handling the gui with limited permissions better
* added a 'comment' field for mappings

this series aims to add a cluster-wide device mapping for (atm) pci and
usb devices. so that an admin can configure a device to be availble
for migration and configuring for uses that are non-root

built-in are some additional safety checks in contrast to current
passthrough, e.g. if pci addresses shift, with the mapping
we can detect that and prevent a vm to boot with the wrong device
(in most cases, there are some edge cases when one has multiple
of the same device, e.g. the same gpu, that we cannot detect)

all in all the series should be functional, but there are some parts
that are not finished/rough:
* the config format
    for now i used a section config with 'hostname:id' as section
    header, but this is not optimal. after some discussion with several
    colleagues, i'll probably settle for a config file with pure json
    in it, since there is no good way to have the necessary nesting
    level (a mapping per node per id + properties per id) and have
    it reasonably integrate in the section config, while maintaining
    ease of use with a normal editor (ideally we would have anoter
    config format like json with comments/trailing commas, or
    rust-object-notation)

    if there are some better ideas, please tell!

* node api
    here the section config helps us, but we have the usual weirdness
    with all options everytime available. also currently the api is
    limited to the node level, and i have no good solution for
    distributing the current state of the devices yet
    (we can use the pvestatd as usual, but it does so many things
    already; the rewrite really becomes a blocker for many things)

* cluster-wide gui
    depends on the cluster wide api call for listing, which i omitted
    for now for the reasons i gave above

* vm editing gui
    not completely happy with the result, but could not come up
    with something better in the time i had until now

* config file location
    for now it lives in pve-common, though after looking at the
    dependency chain, it would be possible to move it to qemu-server
    does not really matter to me, and if we sometime want to extend
    it to containers it needs to be at least in pve-guest-common

* auto-generated roles:
    i did not find a way to have a 'PVEHardwareUser' role without an
    'PVEHardwareAdmin', but the 'Admin' would have the same privs.
    so i settled on only having an Admin. Not sure if that makes sense..

dependencies:
    manager depends on qemu-server,pve-access-control,pve-common
    qemu-server depends on pve-access-control,pve-common
    pve-common depends on pve-cluster

additioanl info:
pve-common 1/3 and 2/3 are necssary but could be independetly applied,
no breaking change
