[pve-devel] [PATCH v2 manager 1/2] api: nodes: allow setting HA shutdown policy during shutdown/reboot

Increases flexibility/user-friendliness.
In the edge case that an override is already present, but the user
doesn't have Sys.Modify privilege, just proceed with the existing
override. Could in principle happen when the requests from a
privileged user with a policy and an unprivileged user without a
policy arrive at the same time.

(Build-)dependency bump for libpve-cluster-perl needed.
Changes in v2:
* Also check for Sys.Modify privilege when parameter is specified.
