Improved short link options in Explore

New in Explore, more options for sharing your query results! The time picker in Grafana has always had two categories - relative (for example, now to 2 hours ago) and absolute (8am to 10am). Explore has allowed people to copy links and create short links with exactly what their time picker had set, but now additionally you have the option to get a link or create a short link with the time range made absolute, even if you are viewing relative time. This means whoever looks at your link will see exactly the data you are seeing, no matter when they open the link. This is available as a dropdown next to the existing shortlink button in Explore.
