[PATCH ha-manager 0/2] fix #7399: check if required rule props are set

[Daniel Kral <d.kral@proxmox.com>]

The API endpoints allow users to set empty 'nodes' and 'resources'
properties for HA rules, which are not handled by the api schema
verification nor the api handlers themselves.

PATCH 1 fixes the

    got unexpected error - cannot lookup undefined type! at
    /usr/share/perl5/PVE/HA/Config.pm line 232.

error message for existing configs with invalid sections, which prevents
the CRM from doing any other progress. It will only keep logging the
hint that a section misses a required option.

PATCH 2 prevents users from passing empty strings for the 'nodes' and
'resources' parameters, which are catched before these are written to
the rules config itself.

A more general solution is proposed in [0], which fixes this behavior in
PVE::SectionConfig itself.
