Trend Display General Improvements

[du5tin]

The trend object is really starting to show its age. I would like to propose some improvements to the UI and interface of the trend object: 

- selectable on/off toolbar with options for ruler, go to now, start/end timestamp filters, and more

- selectable on/off date slider under the x-axis or above the trend. This is common UI element seen in trend features on Azure and Power BI. The user can slide a start and end UI elements across a timeline that represents "now" on the right to various points in the past on the left. Trend start/end timestamps would update accordingly.
