[pve-devel] [PATCH common 3/4] section config: allow separated property lists for plugins

when using 'init(1)'. This saves the property lists per type instead of
a big one, and using create/updateSchema creates a new schema with the
options as 'oneOf' and/or 'instance-types' (depending if the schemas
match).
for that to work there are a few changes in how to use the 'options' hash:
* when wanting to use a property that is not defined in either the local
list or the global one, the 'type' property has to be given to specify
which plugin type this should be taken from
* if it's desired to always have some global properties in the schema,
they have to be given in the 'global' options section now (the perl
package where the base plugin is defined)
for now, we then save the global options in the section '__global',
which is now a forbidden plugin type, but that should be fine as we
don't use that
