/**
 * Handles conversion detection and tracking for tracker requests.
 *
 * ## Request Metadata
 *
 * This processor defines the following request metadata under the **Goals**
 * plugin:
 *
 * * **goalsConverted**: The array of goals that were converted by this request. Each element
 *                       will be an array of goal column value pairs. The ecommerce goal will
 *                       only have the idgoal column set.
 *
 *                       Set in `processRequestParams()`.
 *
 *                       Plugins can set this to empty to skip conversion recording.
 *
 * * **visitIsConverted**: If `true`, the current visit should be marked as "converted". Note:
 *                         some goal conversions (ie, ecommerce) do not mark the visit as
 *                         "converted", so it is possible for goalsConverted to be non-empty
 *                         while visitIsConverted is `false`.
 *
 *                         Set in `processRequestParams()`.
