/**
 * 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.
