[pve-devel] [PATCH v3 guest-common 04/19] helpers: add method to represent config as a table

[Oguz Bektas]

in vm_pending API, this method is used to represent the configuration as
a table with current, pending and delete columns.

by adding it as a guesthelper, we can also use it for container pending
changes.
