* service: is the service expected to have two functions defined. Both of these

* scope in which the action button appears.
*
* 1. allowed(item[s], scope): is expected to return a promise that resolves
* if the action is permitted and is rejected if not. If there are multiple promises that
* need to be resolved, you can $q.all to combine multiple promises into a single promise.
* When using 'row' or 'detail' type, the current 'item' will be passed to the function.
* When using 'batch' type, no arguments are provided.
* 2. perform: is what gets called when the button is clicked. Also expected to return a
* promise that resolves when the action completes.
* When using 'row' or 'detail' type, the current 'item' is evaluated and passed to the
* function.
* When using 'batch' type, 'item' is not passed.
* When using 'delete-selected' for 'batch' type, all selected rows are passed.
* 3. initScope: actions may perform post-config (in the angular sense) initialization by
* providing an initScope method. This might be typically invoked by initActions()
* on a ResourceType. Actions should not perform blocking operations in their
* construction, for example API calls, because as injectables their constructor
* is run during injection, meaning those calls would be executed as the module
* is initialized. This would mean those calls would be blocking on any
* Angular context initialization, such as going to the login page.

deprecations:
- The initScope method for action services has been
deprecated, with the new method initAction added
which does not get passed a scope. The allowed and
perform method are now passed a scope for context
in addition to the first item/items argument.
The "scope" parameter to the WizardModalService modal()
method has also been deprecated, and will be ignored
in a future release of Horizon.
