Hi,

This is an attempt to cleanup current behaviour of cloudinit online changes.

Currently, we setup cloudinit options as pending, until we generate the config drive.

This is not 100% true, because some option like vm name, nic mac address can be changed,
without going to pending, so user can't known if it need to regenerated it.

Also, some can are very difficult to handle, if you hotplug a nic but it's failing,so pending,
then you defined an ipconfig, and then you revert hotplug.
or if you delete a nic, the ipconfig is no more displayed in the gui.


So, instead of setting cloudinit values in pending,
this patch serie copy the current cloudinit config in a new section [special:cloudinit],
when the config drive is generated.
This is only an hint, to allow to display diff between the generated cloudinit
drive, and the current vm config.

A new specific cloudinit config api is added too displaying the diff between current and generated config.

Changelog V1:

- use [special:cloudinit] instead [CLOUDINIT] for section
- delete config section on drive removal
- config api: move code to new PVE::QemuServer::Cloudinit::get_pending_config
- config api: add "qm cloudinit pending" cli
- add update api to regenerate drive with 1 api call
- add cloudinit hotplug option

Changelog v2:

- fix trailing whitespace in first patch
- revert previous "cloudinit" check in snapshot name (":" character is already forbidden)

Changelog v3:

- extract the current conf from cloudinit drive instead write the special cloudinit section

Changelog v4:

- rebase on v2, keep current cloudinit config in vm configuration
- pending api: display mac address change on netX
- cleanup && fix from Fabian comments


Alexandre Derumier (6):
  cloudinit: add cloudinit section for current generated config.
  generate cloudinit drive on offline plug
  cloudinit: make cloudnit options fastplug
  api2: add cloudinit config api
  api2: add cloudinit_update
  add cloudinit hotplug
