Context per render key

In contextPerRenderKey mode, the plugin will reuse the same browser context for all rendering requests sharing the same renderKey auth cookie and target domain within a short time window. Each new request will open a new page within the existing context. Contexts are closed automatically after 5s of inactivity.

In the case of contextPerRenderKey mode, the clustering.max_concurrency option refers to the number of open contexts rather than the number of open pages. There is no limit to the latter.

contextPerRenderKey was designed to improve the performance of the [dashboard previews crawler](TODO: ADD LINK).
