Deeplink Top Pages URLs in the Behavior dashboard

What does this MR do and why?

Adds the ability for dashboard visualizations to define two dimensions as links, one used as text and the other as href:

"options": {
    "links": [
      {
        "text": "TrackedEvents.docPath",
        "href": "TrackedEvents.url"
      }
    ]
  }

When configured, only a single dimension will be displayed (text) but the other will be used as href as a link. This currently only applies to the DataTable.

This is configured on the product analytics Behaviour dashboard, for the Top Pages panel.
