Feature: Adds redux action logging toggle from url params (#17368)

With live tailing introduced in Explore we now have a lot of actions dispatching and the Redux Dev Tools doesn't cope with the amount and rate of actions and crashes. This PR turns on redux action logging when you add logActions=true in the url and turns it off if you refresh the page or add logActions=false in the url.
