[pve-devel] [RFC pve-storage master v1 06/12] plugin: meta: add metadata regarding views in API

["Max R. Carrara" <m.carrara@proxmox.com>]

Define and expose currently possible view types and view modes in
`::Plugin::Meta`.

Add a 'views' array to the objects returned by the 'plugins/storage'
and 'plugins/storage/{plugin}' endpoints, containing all view types
that a plugin currently supports.
