Resource `newrelic_one_dashboard`: Support for Widget Tooltip Configuration

[llaughlin]

Feature Description

Support for the tooltip configuration for dashboard widgets, particularly line graphs.

This basically means supporting tooltip.mode = 'all' in terraform.

Additional context

Example from dashboard JSON:

  ⁝
  "tooltip": {
    "mode": "all"
  },
  ⁝

I had some trouble getting it to work. The terraform apply command succeeded, but the tooltip behavior doesn't seem to have taken effect :\
