Add resource for properties definition

[kwibus]

Multiple resource can have custom properties:

• ranges
• CloudNetworks
• ipam_record
• dnszones

But before you can use them you have to create a custom properties definition.
Can we make 1 resource to do that?

[kwibus]

technical all the custom properties definitions are separate resources in the api:

• /IPAMRecords/{ref}/PropertyDefinitions/{property}
• /Ranges/{ref}/PropertyDefinitions/{property}
• etz

But the all have the same fields so its at least possible

[kwibus]

When setting a custom propertie of a resource. There is no reference made to customPropertie definition.
And i think this is fine, but this means you need to add depends_on = [ menandmice_custom_propertie_definition.<name>] when you set a custom proportie. Otherwise terraform does not know that the resource depends on the definition
