[pve-devel] [PATCH v2 manager 4/6] vzdump: avoid 'requires' constraint when parsing defaults

[Fabian Ebner <f.ebner@proxmox.com>]

to avoid warnings like
parse error in '/etc/vzdump.conf' - 'storage': missing property -
'notes-template' requires this property
when there is no default for the required property configured.

In new(), the defaults are mixed in with the regular CLI/API
parameters, so re-check if the required property is set. If it's not,
the defaults do not apply to the current run, and can be dropped.

Signed-off-by: Fabian Ebner <f.ebner@proxmox.com>

New in v2.
