An action scope defines a "place" for an action to be shown and may add

additional expression variables.

Each QgsAction can be available in one or several action scopes.

Examples:

---------

<dl>

<dt>Canvas</dt>

<dd>Show for canvas tools. Adds `@clicked_x` and `@clicked_y` in map coordinates.</dd>

<dt>Feature</dt>

<dd>Show in feature specific places like the attribute table or feature

form.</dd>

<dt>Field</dt>

<dd>Show in context menus for individual fields (e.g. attribute table). Adds `@field_index`, `@field_name` and `@field_value`.</dd>

<dt>Layer</dt>

<dd>Show in attribute table and work on the layer or selection.</dd>

</dl>

@note Added in QGIS 3.0
