* Handles actions detection and recording during tracker requests.

* ## Request Metadata
*
* This RequestProcessor exposes the following metadata for the **Actions** plugin:
*
* **action**: Contains the `Action` instance that represents the action being tracked for
* the current tracking request.
*
* Set in `processRequestParams()`.
*
* Other RequestProcessors can unset this value to skip actions recording or
* change the value to change how they are recorded.
*
* **idReferrerActionUrl**: The idaction of the URL action that is the referrer for the action
* being tracked.
*
* Set in `processRequestParams()`.
*
* Can be changed/unset to change the current action's referrer action.
*
* **idReferrerActionName**: The idaction of the name action that is the referrer for the action
* being tracked.
*
* Set in `processRequestParams()`.
*
* Can be changed/unset to change the current action's referrer action.
