[pve-devel] [RFC pve-storage master v1 05/12] plugin: add new plugin API method `get_form_view()`

[Max R. Carrara]

This method returns a nested hashref containing the form view
definition for the given plugin in `$class`. The returned hashref must
correspond to the form view schema in the `::Plugin::Views` package.

Plugins that define a form view must specify so in `plugindata()`:

    sub plugindata {
        return {
            # [...]
            views => {
                form => 1,
            },
        };
    }

Returns undef by default otherwise.

`get_form_view()` takes a single parameter (besides `$class`) named
`$context`, which is a hashref that contains additional context vars
that may or may not be taken account by the method.

Currently, the only such context variable is `mode`, which can be
either 'create' or 'update', corresponding to whether a configuration
entry belonging to the plugin is being created or edited (-> updated).
