+ Register an action callback that can be triggered from supporting
+ user interfaces, such as Treeherder.
+
+ This function is to be used as a decorator for a callback that takes
+ parameters as follows:
+
+ ``parameters``:
+ Decision task parameters, see ``taskgraph.parameters.Parameters``.
+ ``input``:
+ Input matching specified JSON schema, ``None`` if no ``schema``
+ parameter is given to ``register_callback_action``.
+ ``task_group_id``:
+ The id of the task-group this was triggered for.
+ ``task_id`` and `task``:
+ task identifier and task definition for task the action was triggered
+ for, ``None`` if no ``context`` parameters was given to
+ ``register_callback_action``.
+
+ Parameters
+ ----------
+ name : str
+ An identifier for this action, used by UIs to find the action.
+ title : str
+ A human readable title for the action to be used as label on a button
+ or text on a link for triggering the action.
+ symbol : str
+ Treeherder symbol for the action callback, this is the symbol that the
+ task calling your callback will be displayed as. This is usually 1-3
+ letters abbreviating the action title.
+ description : str
+ A human readable description of the action in **markdown**.
+ This will be display as tooltip and in dialog window when the action
+ is triggered. This is a good place to describe how to use the action.
+ order : int
+ Order of the action in menus, this is relative to the ``order`` of
+ other actions declared.
+ context : list of dict
+ List of tag-sets specifying which tasks the action is can take as input.
+ If no tag-sets is specified as input the action is related to the
+ entire task-group, and won't be triggered with a given task.
+
+ Otherwise, if ``context = [{'k': 'b', 'p': 'l'}, {'k': 't'}]`` will only
+ be displayed in the context menu for tasks that has
+ ``task.tags.k == 'b' && task.tags.p = 'l'`` or ``task.tags.k = 't'``.
+ Esentially, this allows filtering on ``task.tags``.
+
+ If this is a function, it is given the decision parameters and must return
+ a value of the form described above.
+ available : function
+ An optional function that given decision parameters decides if the
+ action is available. Defaults to a function that always returns ``True``.
+ schema : dict
+ JSON schema specifying input accepted by the action.
+ This is optional and can be left ``null`` if no input is taken.
+ permission : string
+ This defaults to ``generic`` and needs to be set for actions that need
+ additional permissions. It appears appears in ci-configuration and
+ various role and hook
+ names.
+ cb_name : string
+ The name under which this function should be registered, defaulting to
+ `name`. Unlike `name`, which can appear multiple times, cb_name must be
+ unique among all registered callbacks.
+
+ Returns
+ -------
