[pve-devel] applied: [pve-common 1/7] cli: remove all output formatter magic from CLIHandler

[Dietmar Maurer]

- and rename format to 'output-format'

- provide a method to add properties to schema:
	PVE::RESTHandler::add_standard_output_properties

- provide methods to extract output properties:
	PVE::RESTHandler::extract_standard_output_properties()
